Resumo
The Keldysh theorem is generalized to an arbitrary closed operator that is not necessarily close to self-adjoint operators and has a resolvent of Schatten–von Neumann class Sp. Based on this theorem, conditions of spectrum localization are obtained for certain classes of non-self-adjoint differential operators.
