Are solutions of reaction-diffusion equations asymptotically 1D ?

The symmetry of solutions of elliptic equations is a classical and challenging problem in PDE, connected with stability.
In this talk we are concerned with parabolic equations and we ask whether the 1-dimensional symmetry eventually emerges in the long time,

for solutions which are initially non-symmetric.
We will present a satisfactory answer in the case of the Fisher-KPP equation, together with some counter-examples and open questions.
This topic is the object of a joint work with F. Hamel.

Long time behaviour of solutions to Hamilton-Jacobi equations for sub-Riemannian control systems

Sub-Riemannian systems are an important class of nonlinear control systems with linear dependence on controls. Controllability properties for such systems are derived by the so-called Lie Algebra rank condition on the associated family of vector fields. We will discuss the long-time average behaviour of the value function of optimal control  problems for sub-Riemannian systems, which cannot be addressed by classical weak KAM theory as the Hamiltonian fails to be coercive in the momentum variable.
