Période de these : de 1 octobre 2007 à 14 septembre 2010The aim of this work is to study the general nonlinear pseudo parabolic problem: find a real valued measurable function $u$ on $Q:=]0,T[\times \Omega$ solution to \begin{equation*} \left\{ \begin{array}{l@{\quad}l} f\left(t,x,u_t\right)-Div \left\{a\left(x,u,u_t\right)\nabla u+b\left(x,u,u_t\right)\nabla u_t \right\}=g(t,x), \; (t,x)\in Q, \\ u(x,t)=0,\; (t,x)\in ]0,T[\times \partial \Omega, \\ u(0,x)=u_0, \; x\in \Omega,\\ \end{array} \right. \end{equation*} where the operator of Nemestki associated to the function $f$ is monotone.\\ In a first chapter, one shows the existence of a solution to the above problem by the way of the implicit time-semidiscretization. The existence of the s...
