In some important problems of mathematical physics, hydrodynamics, solid state physics, quantum field theory, statistical physics and nonrealistic quantum mechanics, it is important to study the spectral properties of the Friedrich operator in several dynamic problems. in statistical physics, the lattice gas represents the binding state, and in quantum mechanics, the specific values represent the binding states of the energies. Furthermore, the three- and multi-particle systems that emerge in nonreiltivistic quantum mechanics are inextricably linked with the spectral properties of Hamiltonians
