Time-Periodic Linearized Solutions of the Compressible Euler Equations and a Problem of Small Divisors
It has been unknown since the time of Euler whether or not time-periodic sound wave propagation is physically possible in the compressible Euler equations, due mainly to the ubiqui...

An Invariance Principle for Random Traveling Waves in One Dimension
We consider solutions to a nonlinear reaction diffusion equation when the reaction term varies randomly with respect to the spatial coordinate. The nonlinearity is either the ign...

Homogenization of Fronts in Highly Heterogeneous Media
We consider the evolution by mean curvature in a highly heterogeneous medium, modeled by a periodic forcing term, with large L∞ -norm but with zero average. We prove existence o...

Reconstruction of Penetrable Obstacles in Acoustic Scattering
We develop a reconstruction algorithm to determine penetrable obstacles inside a domain in the plane from acoustic measurements made on the boundary. This algorithm uses complex g...

Global Smooth Solutions of Euler Equations for Van der Waals Gases
We prove global in time existence of solutions of the Euler compressible equations for a Van der Waals gas when the density is small enough in Hm , for m large enough. To do so, w...
