## Communicated by A. Piskorek We consider the bidimensional stationary Stefan problem with convection. The problem is governed by a coupled system involving a non-linear Darcy's law and the energy balance equation with second member in ΒΈ. We prove existence of at least one weak solution of the pro

Communicated by G. F. Roach
The goal of this paper is to establish that even for strongly non-linear Darcy's laws and strongly non-linear leaky boundary conditions on the bottom of the reservoirs the fluid flow through a porous dam is a well-posed problem for which existence of a solution can be established. In a simple case we provide also the exact solution to the problem.

Various types of sufficient conditions of optimality for non-linear optimal control problems with delays in state and control variables are formulated. The involved functions are not required to be convex. A secondorder sufficient condition is shown to be related to the existence of solutions of a R
Parallelization of the algebraic fictitious domain method is considered for solving Neumann boundary value problems with variable coefficients. The resulting method is applied to the parallel solution of the subsonic full potential flow problem which is linearized by the Newton method. Good scalabil
