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...

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...
