Abstract

A nonlinear elliptic problem involving $p$-Laplacian and nonlinear boundary condition is considered in this paper. By using the method of Nehari manifold, it is proved that the system possesses two nontrivial nonnegative solutions if the parameter is small enough.

Keywords: $p$-Laplacian systems, nonlinear boundary condition, multiple solutions, Nehari manifold
