The stability of tree-level relations among the parameters of a quantum field theory with respect to renormalization group (RG) running is typically explained by the existence of a symmetry. A simple model of two real scalar fields is presented in which a tree-level relation among the squared-mass parameters of the scalar potential is RG-stable without the presence of a conventional underlying symmetry. Some authors have attempted to explain this result by introducing a so-called GOO Fy symmetry. In this talk, the stability of this parameter relation with respect to RG running is explained by complexifying the original scalar field theory. It is then possible to exhibit a conventional symmetry that guarantees the relations of relevant beta functions of squared-mass parameters of the complexified theory. We can then show that the RG-stability of the parameter relations of the original real scalar field theory is inherited from the conventional symmetry of the corresponding complexified theory.

Multivariate Hawkes processes form a class of point processes describing self and inter exciting/inhibiting processes. There is now a renewed interest of such processes in applied domains and in machine learning, but there exists only limited theory about inference in such models apart from parametric models. After reviewing results on convergence rates for Bayesian nonparametric approaches to such models, I will present new results on uncertainty quantification for important functionals.

Glacierized mountainous areas make up some of the most hazardous landscapes of our planet, and are undergoing profound changes under 21st century climatic warming. The answers to two fundamental questions are required in these areas: (i) what is the baseline hazard and risk, and (ii) are the hazard and risk likely to increase or decrease in coming decades. While these questions remain largely unanswered on a global scale, this presentation delves into the subject through a series of case studies of complex hazards in glacierized and high-mountain areas.

In this talk, I will consider both the gaps in our current knowledge, and how novel techniques and datasets help bridge these. In particular, I will discuss the two-way interactions between landslides and glaciers, improving summit ice volume estimates at glacierized volcanoes, and new optical feature tracking approaches to map slope deformation the scale of mountain ranges. The evolving hazard profile intersects with a growing population and rapidly developing infrastructure networks. As a result, a cross-disciplinary approach is essential to comprehensively analyse and mitigate risk. This talk highlights the significance of addressing these challenges and explores avenues for future research.

Particle-driven convection occurs when a dense particle-laden layer settles into a layer of clear fluid. This can drive a variation on the classical Rayleigh-Taylor instability, where particles induce the density difference between the two fluids. Variants of this instability occur in many geophysical flows, such as the undersides of volcanic ash clouds, sediment-laden river outflows, and the dynamics of droplets in clouds. This talk will present some new experimental results of Rayleigh-Taylor instability occurring between a particle-laden and fresh-water layers. I will also present some preliminary results that examine the effect of adding salt to the lower layer. For this second case, the initial stratification is stable, but becomes unstable due to particle settling.
