Système d'Euler incompressible et régularité microlocale analytique

Pascal Gamblin (1994)

Annales de l'institut Fourier

Dans cet article on étudie la régularité analytique (ou Gevrey) des courbes intégrales de champs de vecteurs solutions non nécessairement lipschitziennes du système d’Euler incompressible. On en déduit que le front d’onde analytique (ou Gevrey) de ces solutions est localisé dans la variété caractéristique de l’opérateur linéarisé.

Systems of reaction-diffusion equations with spatially distributed hysteresis

Pavel Gurevich, Sergey Tikhomirov (2014)

Mathematica Bohemica

We study systems of reaction-diffusion equations with discontinuous spatially distributed hysteresis on the right-hand side. The input of the hysteresis is given by a vector-valued function of space and time. Such systems describe hysteretic interaction of non-diffusive (bacteria, cells, etc.) and diffusive (nutrient, proteins, etc.) substances leading to formation of spatial patterns. We provide sufficient conditions under which the problem is well posed in spite of the assumed discontinuity of...

Systems with Coulomb interactions

Sylvia Serfaty (2014)

Journées Équations aux dérivées partielles

Systems with Coulomb and logarithmic interactions arise in various settings: an instance is the classical Coulomb gas which in some cases happens to be a random matrix ensemble, another is vortices in the Ginzburg-Landau model of superconductivity, where one observes in certain regimes the emergence of densely packed point vortices forming perfect triangular lattice patterns named Abrikosov lattices, a third is the study of Fekete points which arise in approximation theory. In this review, we describe...
