Abstract
This Paper is devoted to a proof of a stability result on the solutions of the equation on an open bounded set of , where p∗stands for the critical exponent for the Sobolev embedding of W 1-pinto Lk spaces, and Δ p for the p-Laplacian operator. In particular, we use the concentration-compactness theorem of P.L.Lions in order to prove that, under some assumptions on the data, the solutions cannot converge to 0.
