In this talk, I will review some of the recent results on the Stochastic Heat Equation (SHE) with multiplicative white noise in dimension d=2. The SHE is a stochastic PDE which is ill-defined in its critical dimension d=2 : in that case, very recent results show that a subtle normalisation procedure is needed to make sense of it. I will present the probabilistic approach to this normalisation procedure, followed by Caravenna, Sun, Zygouras : it is based on the study of the directed polymer model, a statistical mechanics model which can be seen as a discretised version of the SHE . In a very specific critical window for the parameters, the model possess a non-trivial scaling limit, that Caravenna, Sun, Zygouras called Critical 2D Stochastic Heat Flow, and can be interpreted as a (notion of a) solution to the 2D SHE . I will then review some of the properties of this Stochastic Heat Flow and present some of the results based on a joint work with F. Caravenna and N. Turchi.

The Constraint Satisfaction Problem (CSP) is a type of decision problem with several equivalent formulations. Its original definition was inspired by considerations in Descriptive Complexity, and represents a large part (in some sense) of the class NP. However, any CSP was famously conjectured to be either tractable, or NP-complete, and this was proved independently in 2017 by Bulatov and by Zhuk. I will recall various approaches which were attempted in the quest for the Dichotomy Conjecture, until the methods of Universal Algebra, via polymorphisms of the model, finally bore fruit. Next I will outline Zhuk\s proof of the Dichotomy Conjecture in broad strokes, in particular various types of reductions he used. In the final part I will show the recent result where we proved that just one of the reductions of Zhuk is sufficient to emulate all others and prove the Dichotomy. I will end the lecture explaining why this is not (yet!) a short proof of the Dichotmy, and discuss what our result does show.

Semiring provenance was originally introduced in database theory with the aim of explaining why certain tuples are (not) contained in the answer of a query — to explain their provenance. To this end, logical statements are not just evaluated to true or false but by values from a commutative semiring. This allows us to track which combinations of atomic facts are responsible for the truth of a statement and to derive practical information about costs, access levels, or confidence scores. Recently, this approach has been expanded to a systematic study of semiring semantics for first-order logic and other logical systems. This talk gives an overview of the recent results on the generalisation of model-theoretic properties and methods such as compactness, Ehrenfeucht-Fraïssé games, or locality beyond the Boolean semiring. Many model-theoretic notions admit natural generalisations to the semiring framework (e.g. entailments can be understood as inequalities of semiring valuations) while even simple properties lead to surprisingly difficult questions that require new proof techniques. It turns out that most of the classical logical results and methods can be generalised to some semirings but fail for others. We shall discuss how this is related to algebraic properties of the underlying semirings such as idempotence and absorption.

Abstract

From the first lullabies that soothe an infant to the anthems of adolescence, song traces the map of our becoming. More than entertainment, it is a medium through which children learn to attend, remember, speak, and feel with others. This lecture follows development from infancy through adolescence to show how song supports language growth, memory formation, emotional regulation, and social connection. I will use brief examples from Arabic, French, and American children’s songs. These examples will show how familiar repertoire reflects cultural identity in language, imagery, and style. They will also show shared design features such as repetition, small pitch ranges, and a steady beat, which support learning and belonging. Drawing on music education, psychology, and neuroscience, I will outline what changes across stages and what endures: the voice as the most immediate instrument, rhythm as an organizer of attention, and shared singing as a practice that builds trust and community. Practical implications for families, schools, and community programs will include simple routines that nurture resilience and inclusive classrooms. In an age of uncertainty, song remains a durable resource for growth and cohesion, binding individuals to themselves, to one another, and to the wider world.

Abstract

Between 1936 and 1948, Palestinian music experienced a transformative period shaped by the establishment of the Palestine Broadcasting Service (PBS) and the Near East Broadcasting Station (NEBS). These radio stations became influential cultural platforms that enabled Palestinian musicians to explore, refine, and project a national identity through music. They created an ecosystem in which diverse traditions could intermingle, inviting voices from across Palestine and the broader Arab region to contribute to a vibrant musical landscape. Within this environment, vocal genres underwent significant evolution, as traditional folk melodies expanded into shaʿbī songs and new forms such as the Palestinian Qaṣīda emerged. Instrumental compositions also flourished, crafted for both local and Western ensembles, while choirs and children’s programming deepened the reach of musical production. Palestinian musicians simultaneously engaged with Egyptian popular styles and preserved classical traditions, including the muwashshaḥāt. The opportunities for recording and broadcasting provided by PBS and NEBS not only elevated the visibility of Palestinian musicians but also ensured the preservation and dissemination of their works. This cultural renaissance, marked by innovation and cross-cultural exchange, fostered a distinctive Palestinian musical identity that reflected both regional diversity and local creativity.

Abstract

We have no shortage of evidence about the importance of song in the ancient world, including written descriptions of music in literature, songs embedded in narratives, standalone hymnic texts, and collections of psalms and hymns. While we can only imagine the melodies and modes of performance, the surviving texts reveal an imaginal world in which the divine and the human were inextricably interwoven. In Greco-Roman antiquity we see how songs of one time and place became an evocative source for later generations to reflect on their particular realities in light of larger forces they saw at work in the world, including in the divine benefactions of their rulers. Early Jewish and Christian psalms and hymns show that their authors had complex ways of reworking traditions and themes to meet the needs of a new era, both religiously and politically. This lecture explores the rich treasury of ancient religious song, looking especially at how songs functioned for the communities that preserved them. We will pay attention to the affective dimensions of ancient songs, their power to shape a community’s perception of reality, and their suitability to serve as vehicles of resistance through the reimagining of earlier images and forms. If we listen carefully, even today we can hear echoes of religion and resistance in the songs of antiquity.

Biography

Matthew E Gordley is a scholar of Christianity and Judaism in antiquity who has been researching and writing on the influence and impact of ancient song for more than two decades. His work on early Christian and Jewish psalms and hymns seeks to situate these poetic compositions within their ancient historical and cultural contexts so that they may be more fully appreciated by readers today. His scholarly monographs on the subject include The Colossian Hymn in Context (2007), Teaching through Song in Antiquity: Didactic Hymnody among Geeks, Romans, Jews, and Christians (2011), and New Testament Christological Hymns: Exploring Texts, Contexts, and Significance (2018). His latest book, Social Justice in the Stories of Jesus: The Ethical Challenge of the Parables (2024), uses a similar historical and cultural approach to understand how the stories Jesus told continue to engage and challenge readers to this day. He earned a PhD from the University of Notre Dame and currently serves as Interim Provost and Dean of the College of Arts and Sciences at Carlow University (Pittsburgh, PA), where he also holds a tenured faculty appointment as Professor of Theology.

Abstract

“Throat-singing” is timbre-centred vocal music typified by the simultaneous separate sounding of a musical drone and its overtones or undertones by a solo vocalist. Here I also include the timbral vocal technique of heroic epic performers. Often perceived as otherworldly, these vocal sounds have entranced global listeners and inspired many to attempt the technically difficult styles and substyles. My extensive fieldwork among Indigenous nomadic peoples of Inner Asia, the cradle of this genre, revealed how these sounds “place” the bodies of performers and listeners in the local acoustic landscape and mountain-steppe ecology, enable nomadizing along cross-border pathways in an animist tripartite universe, and create kinship relations with living and ancestral humans and spirits. Tyvan “throat-singer” Radik Tülüsh’s suggestion that these connections form a “philosophy”, inspired my theory of “ontological musicality,” that is, an inter-relational musical complex that connects Inner Asian nomadic identities, ways of being, spirituality, personhood, community, and senses of place. Finally, I ask: can Inner Asian “throat-singing” as an ontological musicality, with its respect for the environment and mediation of the potentially opposing notions of movement and place, be of equal relevance to its technical accomplishment in our own “ways of being” in the world?

Abstract

Since two decades it is possible to measure the seismic activity of stars with high precision. This is thanks to dedicated telescopes operating from space. Using these recorded ‘songs of the stars’, asteroseismologist can gaze into stellar interiors. By doing this, it is possible to probe the physical conditions and chemical composition of these hot balls of gas millions of light years away. Asteroseismology is a unique and powerful tool to determine the size, mass, and age of stars to a higher precision than ever before. It also offers a way to better understand the fastest rotators in the Universe on their way to supernova explosions and gravitational waves. Using the insights gained, astrophycists are able to perform archaeology in our Milky Way galaxy, and to characterise exoplanets. In this talk, 2022 Kavli and 2024 Crafoord Laureate Conny Aerts will explain how to use the songs of the stars to unravel their stories and to see the invisible.

Biography

Conny Aerts graduated as mathematician from Antwerp University (1988) and defended her PhD thesis in astrophysics at KU Leuven (1993). Competitive personal grants allowed her to work as independent postdoctoral fellow of the Research Foundation Flanders (1994 – 2001), performing numerous stays in Europe, Chile and the USA . She was appointed as Lecturer (2001), Associate Professor (2004), and Full professor (2007) at KU Leuven. She also leads the Chair in Asteroseismology at the Radboud University Nijmegen (NL, 2004+) and is External Scientific Member of the Max Planck Society (Heidelberg, 2019+).

Conny’s research covers stellar astrophysics, including stellar structure & evolution and variable stars. She is a pioneer of asteroseismology, which received a major boost thanks to the CoRoT (2006+), Kepler (2009+), and TESS (2018+) space missions. Prior to high-precision space photometry, Conny developed rigorous mathematical methods to detect and identify non-radial stellar oscillations in high-resolution time-series spectroscopy. Her team also designed and applied statistical classification methods in a machine-learning context, discoving numerous gravity-mode pulsators in space photometry. As Chair in Asteroseismology at the Radboud University Nijmegen, Conny introduced herself into the topic of subdwarf stars, their binarity and pulsations, with current focus on development and exploitation of BlackGEM in tandem with gravitational wave studies.

In 2008, Conny was awarded an ERC Advanced Grant, PROSPERITY to exploit CoRoT and Kepler space photometry. Her PhD students made major contributions, such as the discovery of non-radial pulsation modes, of dipole mixed modes, and of non-rigid rotation in red giants, following her own detections of internal mixing and rotation in massive stars. The ERC offered her a 2nd AdG, MAMSIE (Mixing and Angular Momentum tranSport in massIvE Stars, 2016-2021) to bridge stellar physics, asteroseismology, and 3D simulations in order to quantify limitations in stellar evolution theory. This culminated in the 2012 Francqui Prize and the 2020 5-year FWO Excellence Award, also termed Belgian and Flemish Nobel Prizes, where Conny was the first woman to receive these prestigious awards in Science & Technology since their creation in 1933 and 1960, respectively. Conny is the recipient of the 2022 Kavli prize in Astrophysics and the 2024 Crafoord Prize in Astronomy; she acts as corresponding Principle Investigator of the 2022 ERC Synergy grant 4D-STAR.

Abstract

The early 20th century in Vienna saw an extraordinary flowering of talent and creativity in music, literature and visual art, as well as in philosophy and psychology. This period is particularly known for the networks of personal and professional relationships that linked creative people in different fields, such as the painter Gustav Klimt, the composer Arnold Schoenberg and the writer Hugo von Hofmannsthal. Until recently, however, the contribution of women to Vienna’s artistic life, has largely been ignored. This lecture shows how research into the lives and musical creativity of some of Vienna’s outstanding women musicians can help us to rethink Vienna’s artistic networks, enlarging our understanding of this extraordinary period, as well as rediscovering some fascinating lives and some exceptional music.

Abstract

From Renaissance princes and popes to modern-day democrats and dictators, those who rule countries, religious communities and empires have often kept a close watch on singers, songs and those who compose them. Equally, song has often been used as a subversive weapon, a tool of protest and a call to arms, as well as to bolster communal or national pride and morale. The tensions around songs and singers are no less prominent today than in the past, as is shown by the recent controversies surrounding what gets broadcast from the Glastonbury Festival, who gets to sing at Covent Garden, or which nations are allowed to compete in the Eurovision Song Contest. But does music have a real capacity to change society, rather than merely acting as a vent for strong emotions? How does singing affect us as individuals? Can it actually make us feel better – physically, mentally and spiritually? Can it change minds? Conversely, can the withdrawal of opportunities to sing, whether for political, religious or medical reasons, be regarded as a crime against humanity? And does the act of singing as a community bind us together, or reinforce tribal divisions?

The ERC offered her a 2nd AdG, MAMSIE (Mixing and Angular Momentum tranSport in massIvE Stars, 2016-2021) to bridge stellar physics, asteroseismology, and 3D simulations in order to quantify limitations in stellar evolution theory. This culminated in the 2012 Francqui Prize and the 2020 5-year FWO Excellence Award, also termed Belgian and Flemish Nobel Prizes, where Conny was the first woman to receive these prestigious awards in Science & Technology since their creation in 1933 and 1960, respectively. Conny is the recipient of the 2022 Kavli prize in Astrophysics and the 2024 Crafoord Prize in Astronomy; she acts as corresponding Principle Investigator of the 2022 ERC Synergy grant 4D-STAR.

Abstract

From the first lullabies that soothe an infant to the anthems of adolescence, song traces the map of our becoming. More than entertainment, it is a medium through which children learn to attend, remember, speak, and feel with others. This lecture follows development from infancy through adolescence to show how song supports language growth, memory formation, emotional regulation, and social connection. I will use brief examples from Arabic, French, and American children’s songs. These examples will show how familiar repertoire reflects cultural identity in language, imagery, and style. They will also show shared design features such as repetition, small pitch ranges, and a steady beat, which support learning and belonging. Drawing on music education, psychology, and neuroscience, I will outline what changes across stages and what endures: the voice as the most immediate instrument, rhythm as an organizer of attention, and shared singing as a practice that builds trust and community. Practical implications for families, schools, and community programs will include simple routines that nurture resilience and inclusive classrooms. In an age of uncertainty, song remains a durable resource for growth and cohesion, binding individuals to themselves, to one another, and to the wider world.

Abstract

The early 20th century in Vienna saw an extraordinary flowering of talent and creativity in music, literature and visual art, as well as in philosophy and psychology. This period is particularly known for the networks of personal and professional relationships that linked creative people in different fields, such as the painter Gustav Klimt, the composer Arnold Schoenberg and the writer Hugo von Hofmannsthal. Until recently, however, the contribution of women to Vienna’s artistic life, has largely been ignored. This lecture shows how research into the lives and musical creativity of some of Vienna’s outstanding women musicians can help us to rethink Vienna’s artistic networks, enlarging our understanding of this extraordinary period, as well as rediscovering some fascinating lives and some exceptional music.

Biography

Dr Carola Darwin combines a career as an opera and concert singer with research and writing about music. She teaches musicology at the Royal College of Music in London and recently published chapters in The Routledge Companion to Women and Musical Leadership: The Nineteenth Century and Beyond (Routledge 2024) and Elizabeth Maconchy in Context (Cambridge University Press, forthcoming in 2026). Her research into the Viennese composer Johanna Müller-Hermann was part of BBC Radio 3’s Forgotten Women Composers project and was the basis for a recent Composer of the Week on Müller-Hermann, for which Carola was also interviewed. In 2019 she was awarded an Arts Council grant to commission a new work by Cheryl Frances-Hoad, setting texts about evolution and the environment ,which she premièred at the Oxford Lieder Festival. Carola is currently writing a book – The Other Voice: Women musicians in Alma Mahler’s Vienna, to be published by Equinox. Her CD of songs by Viennese composers Johanna Müller-Hermann and Mathilde Kralik (recorded with pianist Marie-Noëlle Kendal) is due to be released in 2026.

The Constraint Satisfaction Problem (CSP) is a type of decision problem with several equivalent formulations. Its original definition was inspired by considerations in Descriptive Complexity, and represents a large part (in some sense) of the class NP. However, any CSP was famously conjectured to be either tractable, or NP-complete, and this was proved independently in 2017 by Bulatov and by Zhuk. I will recall various approaches which were attempted in the quest for the Dichotomy Conjecture, until the methods of Universal Algebra, via polymorphisms of the model, finally bore fruit. Next I will outline Zhuk\s proof of the Dichotomy Conjecture in broad strokes, in particular various types of reductions he used. In the final part I will show the recent result where we proved that just one of the reductions of Zhuk is sufficient to emulate all others and prove the Dichotomy. I will end the lecture explaining why this is not (yet!) a short proof of the Dichotmy, and discuss what our result does show.
