Propagation Of Singularities for Semilinear Hyperbolic Equations
In this paper we use a particular kind of weighted Sobolev space and pseudo-differential operators to study H3s propagation of singularities for the solution u ∊ Hs of the equations with second order.

Hyperbolic to Parabolic Relaxation Theory for Quasilinear First Order Systems
In this paper we study the limiting behavior of nonhomogeneous hyperbolic systems of balance laws when the relaxed equilibria are described by means of systems of parabolic type.

Relaxation Approximations to Front Propagation
We introduce a relaxation model for front propagation problems. Our proposed relaxation approximation is a semilinear hyperbolic system without singularities. It yields a direction-depedent normal velocity at the leading term and captures, in the Chapman–

International audienceWe consider a wave equation with semilinear porous acoustic boundary conditions. This is a coupled system of second and first order in time partial differential equations, with possibly semilinear boundary conditions on the ...

Singular limits for nonlinear hyperbolic systems
The paper is concerned with singular limits for the nonlinear hyperbolic system Wt+A(x,W,D)W=1εF(W),(1) where W=W(x,t) takes values in RN, x∈Rd, A(x,W,D) is a first-order differential or pseudodifferential operator, F(W) denotes the nonhomogeneous term,

On Dynamics and Bifurcations of Nonlinear Evolution Equations Under Numerical Discretization
This article reviews recent results on long-time behaviour, invariant sets and bifurcations of evolution equations under discretization by numerical methods. The emphasis is on time discretization.
