The Dirac Equation in the Model With a Maximal Mass

Abstract

In paper within the model with a maximal mass M and with use of anti de Sitter space is considered the Dirac equation properties for a fermion of mass m on the mass surface. The paper shows that free Hamiltonian and Hamiltonian with interaction are pseudo-Hermitian. If we accept the appropriate rules of use of pseudo-Hermitian Hamiltonians, we can construct the consistent quantum theory with final results obtained using the ordinary Dirac equation.
