Abstract:
The Hamiltonian of a system of four arbitrary quantum particles with three-particle short-range interaction potentials on a three-dimensional lattice is examined. The location of the essential spectrum of this Hamiltonian is described by Faddeev's equations.
Key words:
Schrödinger operator, Faddeev's equations, essential spectrum, compact operator, positive operator.
