Abstract:Based on the generalized Green formula for a sesquilinear nonsymmetric form for the Laplace operator, we consider spectral nonself-adjoint problems. Several such problems are similar to classical ones; others arise in problems of hydrodynamics and diffraction and in problems with surface dissipation of energy. Properties of solutions of such problems are considered. Also, we study initialboundary value problems generating the considered spectral problems and prove correct solvability theorems for such problems… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
