摘要：
We study the asymptotic behaviour (t --> + infinity) of the solutions of a nonlinear diffusion problem with strong absorption. We prove convergence to the stationary solution in the L (infinity) by means of an appropriate family of sub and super-solutions. In appendix we prove the well posedness of the problem.
