Abstract:
We consider a model operator acting in a subspace of a Fock space and obtain a symmetrized analogue of the Faddeev equation. For the operator considered, we describe the position and the structure of its essential spectrum.
Keywords:
creation and annihilation operators, essential spectrum, positive operator, compact operator.
