Eigenvalues of the negative $(p,q)$-Laplacian under a Steklov-like boundary condition

Luminita Barbu, Gheorghe Morosanu

In this paper we consider in a bounded domain $\Omega \subset {\mathbb{R}}^N$ with smooth boundary an eigenvalue problem for the negative $(p,q)$-Laplacian with a Steklov type boundary con…
