Title: Existence and multiplicity of solutions for a Steklov problem involving the p(x)-Laplace operator Authors: Mostafa Allaoui (Univ. Mohamed I, Oujda, Morocco) Abdel Rachid El Amrouss (Univ. Mohamed I, Oujda, Morocco) Anass Ourraoui (Univ. Mohamed I, Oujda, Morocco) Abstract: In this article we study the nonlinear Steklov boundary-value problem $$\displaylines{ \Delta_{p(x)} u=|u|^{p(x)-2}u \quad \hbox{in } \Omega, \cr |\nabla u|^{p(x)-2}\frac{\partial u}{\partial \nu}=\lambda f(x,u) \quad \hbox{on } \partial\Omega. }$$ Using the variational method, under appropriate assumptions on f, we obtain results on existence and multiplicity of solutions.
