Existence of solutions for Dirichlet quasilinear systems including a nonlinear function of the derivative

Shapour Heidarkhani, Massimiliano Ferrara, Ghasem A. Afrouzi, Giuseppe Caristi, Shahin Moradi

Abstract:
In this article we establish the existence of at least one non-trivial classical solution for Dirichlet quasilinear systems with a nonlinear dependence on the derivative. We use variational methods for smooth functionals defined on reflexive Banach spaces, and assumptions on the asymptotic behaviour of the nonlinear data.
