摘要

For a C ~2-functional J defined on a Hilbert space X, we consider the set N={x∈A:projVx?;J(x)=0}, where A?X is open and V _x?X is a closed linear subspace, possibly depending on x~∈A. We study sufficient conditions for a constrained critical point of J restricted to N to be a free critical point of J, providing a unified approach to different natural constraints known in the literature, such as the Birkhoff-Hestenes natural isoperimetric conditions and the Nehari manifold. As an application, we prove multiplicity of solutions to a class of superlinear Schr?dinger systems on singularly perturbed domains.
