Towards Solving Compactified Imaginary Liouville Theory
Yang XIAO (I2M)
On a given Riemann surface, C. Guillarmou, A. Kupiainen, and R. Rhodes constructed a path integral based on the Liouville action functional with imaginary parameters, [...]

Phase transitions in charged polymer models
Julien POISAT (Université Paris Dauphine)
I will review some old and recent results on the topic of charged polymer models. Those are random walk models with disordered interaction at self-intersections, [...]

Recent developments in analysis on spaces of measures.
Charles BERTUCCI (Université Paris Dauphine)
I will present two natural ways to look at functions defined on spaces of (probability) measures, one arising from the linear structure of the space [...]

How to construct a planar Brownian motion from simple path and loops
Isao Sauzedde (ENS Lyon)
During this talk, I will present a joint paper with N. Berestycki in which we introduce and study a map which takes as inputs a [...]

Mean-field analysis of the training dynamics of two-layer neural networks
Arnaud Descours (ISFA, Lyon)
Training neural networks via stochastic gradient descent (SGD) amounts to solving a complex, non-convex optimization problem. Inspired by statistical mechanics, the mean-field approach provides a [...]

The partition function of β-ensembles with complex potentials
Alex Little (ENS Lyon)
The asymptotic behaviour of the partition function is one of the central questions of statistical mechanics. In our work we consider this problem when the [...]
