On the essential spectrum of a model operator associated with the system of three particles on a lattice
A model operator H associated with the system of three-identical particles on a lattice Z3 is considered. The location of the essential spectrum of H is described by the spectrum of the corresponding Friedrichs model, that is, the two-particle and three-particle branches of the essential spectrum of...
