Abstract:

In this paper, we study the existence and multiplicity of nontrivial solutions for a class of quasilinear elliptic systems involving nonhomogeneous nonlinearities and nonlinear boundary conditions. By using the Mountain Pass Theorem and the Ekeland's variational principle, we prove that the system has at least two nontrivial solutions when the parameter λ belongs to a certain subset of R.

Key words: Existence, Multiplicity, Nonhomogeneous, Nonlinear boundary conditions
