Bifurcation Problems for Equations of Elliptic Type with Discontinuous Nonlinearities

D. K. Potapov

Saint-Petersburg State University

Abstract: We consider the problem of the existence of semiregular solutions to the main boundary-value problems for second-order equations of elliptic type with a spectral parameter and discontinuous nonlinearities. A variational method is used to obtain the theorem on the existence of solutions and properties of the “separating” set for the problems under consideration. The results obtained are applied to the Goldshtik problem.

Keywords: second-order equation of elliptic type, bifurcation problem, semiregular solution, Carathéodory function, Dirichlet boundary condition, Neumann boundary condition
