Uniqueness and approximation of solutions of first order non linear equations

Uniqueness and approximation of solutions of first order nonlinear equations

Uniqueness and approximation of solutions of first order non linear equations

Abstract

Soit \(\Omega =]0,T[\times \omega\), où \(\omega\) est un voisinage ouvert de 0 dans \({\mathbb{R}}^ N\), l'A. montre que toute solution de classe \(C^ 2\) du problème \[ (1)\quad \partial u/\partial t=F(t,x,u,\nabla u),\quad u(0,x)=\phi (u) \] est unique dans un voisinage de \(0\subset {\bar \Omega}\) (théorème 1.1.1). L'unicité dépend de l'approximation de u par une suite \(u_{\lambda}\in C^ 2(\Omega_ 0)\), où les \(u_{\lambda}\) sont solutions du problème (1) par une donnée initiale \(\phi_{\lambda}\) analytique, les \(u_{\lambda}\) étant également solution d'une équation implicite (lemme 2.3.1). Il faut de plus montrer que les \(u_{\lambda}\) sont définies sur un même voisinage \(\Omega_ 0\) de 0 (paragraphe 4).
