Steklov-Neumann Eigenproblens: A Spectral Characterization of the Sobolev Trace Spaces

On Steklov–Neumann boundary value problems for some quasilinear elliptic equations

“…Eigenvalue problems have been studied extensively by several researchers, but we refer the reader to [1][2][3][4] and the references therein. For further details of eigenvalue problems that involve the p-Laplacian operator, the reader may refer to [5][6][7] and the references therein.…”
