The collapse of a wedge-shaped dam containing uid initially with a uniform velocity can be described as an expansion problem of gas into vacuum.It is an importa
In this talk I present a recent result about the free boundary problem for 2D current-vortex sheets in ideal incompressible magneto-hydrodynamics near the trans
The talk is devoted to the study of the time-asymptotic stability of rarefaction waves for the Vlasov-Poisson-Boltzmann system in the whole space with slab symm
This talk is devoted to the well posedness issue for the self-gravitating Hookean elastodynamics in dimension three.The solution is constructed near an equilibr
We investigate transmission problems between a(thermo-)viscoelastic system with Kelvin-Voigt damping,and a purely elastic system.It is shown that neither the el
Nonlocality is ubiquitous in nature.We present some nonlocal balance laws that may be seen as generalizations to classical,local balance equations.These nonloca
In this talk,we consider a piston problem for the unsteady two-dimensional Euler system for a Chaplygin gas.The piston is assumed to proceed or recede to a stat
