2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/160908We study generalized Robin boundary conditions, Robin-to-Dirichlet maps, and Krein-type resolvent formulas for Schrödinger operators on bounded Lipschitz domains in $\bbR^n$, $n\ge 2$. We also discuss the case of bounded $C^{1,r}$-domains, $(1/2)<r<1$.61 pages, typos corrected, new material addedAnalysis of PDEsSpectral Theory35J10, 35J25, 35Q40 (Primary); 35P05, 47A10, 47F05 (Secondary)Generalized Robin Boundary Conditions, Robin-to-Dirichlet Maps, and Krein-Type Resolvent Formulas for Schrödinger Operators on Bounded Lipschitz Domainstext
