Time--Splitting Schemes and Measure Source Terms for a Quasilinear Relaxing System
Laurent Gosse
Several singular limits are investigated in the context of a system arising for instance in the modeling of chromatographic processes. In particular, we focus on the c…
Resolution of the finite Markov moment problem
Laurent Gosse, Olof Runborg
We expose in full detail a constructive procedure to invert the so--called "finite Markov moment problem". The proofs rely on the general theory of Toeplitz matrices together with…
Existence, uniqueness and a constructive solution algorithm for a class of finite Markov moment problems
Laurent Gosse, Olof Runborg
We consider a class of finite Markov moment problems with arbitrary number of positive and negative branches. We show criteria for the existence and uniqueness of solutions, and we…
Chirplet approximation of band-limited, real signals made easy
J. M Greenberg, Laurent Gosse
In this paper we present algorithms for approximating real band-limited signals by multiple Gaussian Chirps. These algorithms do not rely on matching pursuit ideas. They are hierar…
Numerical aspects of nonlinear Schrodinger equations in the presence of caustics
Rémi Carles, Laurent Gosse
The aim of this text is to develop on the asymptotics of some 1-D nonlinear Schrodinger equations from both the theoretical and the numerical perspectives, when a caustic is formed…
