Aim of the workshop

This workshop corresponds to a meeting between two funding ANR projects: METANOLIN and QuAMProcs. The main common objective of the two teams is to tackle metastability problems. Roughly speaking, the metastability problems arise when one is interested in intricate optimization problem involving method related to stochastic gradient approach. Although metastability is well understood from decades for linear and reversible diffusions, the two projects are dealing with setting where the classical techniques are not efficient. In this workshop, we gather experts for the questions of metastability in high dimensional setting (mean field particle systems) and in non linear one. The particularity of the nonlinear processes is that they satisfy some stochastic differential equations where there is no linearity (with respect to the associated partial differential equation). The linear stochastic processes had been well known for decades. But, the nonlinear ones are the subject of intense research in the domain of the probability, in the partial differential equations but also in the applications of the mathematics. However, real phenomena are more often nonlinear processes than linear one. Let us give some examples of nonlinear processes that we are interested in: the self-stabilizing diffusion, McKean-Vlasov diffusion for modelling lithium batteries, neural networks and the self-interacting diffusion.
