Abstract: We consider a Hamiltonian of a system of four arbitrary quantum particles with pair contact (noncompact) potentials on a three-dimensional lattice perturbed by three-partial contact potentials. We describe the essential spectrum of the Schrödinger operator that corresponds to the four-particle system.
Keywords: Hamiltonian of a four-particles system, Schrödinger operator, essential spectrum, compact operator.
