Constant-sign solutions for a nonlinear Neumann problem involving the discrete p-Laplacian
Abstract. In this paper, we investigate the existence of constant-sign solutions for a nonlinear Neumann boundary value problem involving the discrete \(p\)-Laplacian. Our approach is based on an abstract local minimum theorem and truncation techniques.
Keywords: constant-sign solution, difference equations, Neumann problem.
