Sobolev $(p, q)$ -extension operators and Neumann eigenvalues

Vladimir Gol'dshtein, Alexander Ukhlov

In this article, we consider $(p, q)$ -extension operators, $1 < q \leq p < \infty$ , on Sobolev spaces. Based on composition operators on Sobolev spaces, we construct the extension op…

On the weighted Steklov eigenvalue problems in outward cuspidal domains

Prashanta Garain, Vladimir Gol'dshtein, Alexander Ukhlov

In this article, we investigate the weighted Steklov eigenvalue problem and the weighted Schrödinger--Steklov eigenvalue problem in outward cuspidal domains. We prove the solvabili…
