Asymptotic formulae for the Schrodinger operator with Dirichlet and Neumann boundary conditions
No full textIn this paper, we consider the Schrodinger operators defined by the differential expression Lu = -Delta u+q(x)u in d-dimensional parallelepiped F, with the Dirichlet and Neumann boundary conditions, and obtain the asymptotic formulae for the eigenvalues of these operators
