Abstract

In this study, we consider the first eigenvalues associated with the q-Wentzell-Laplace problem on a compact submanifold M that possesses a boundary ?M and we obtain Reilly-type upper bounds for these eigenvalues. Our findings, in particular scenarios, align with the results presented in 14. Additionally, we investigate the upper bounds of these eigenvalues within the context of product manifolds R ? M.
