Study of the essential spectrum of a matrix operator
T. H. Rasulov Bukhara State University, Bukhara, Uzbekistan
Abstract:
We consider a matrix operator $H$ corresponding to a system with a nonconserved finite number of particles on a lattice. We describe the structure of the essential spectrum of the operator $H$ and prove that the essential spectrum is a union of at most four intervals.
Keywords:
matrix operator, system with a nonconserved finite number of particles, Fock space, generalized Friedrichs model, essential spectrum, eigenvalue.
