    "abstract": "The thesis is devoted to the phase space representation of relativistic\nquantum mechanics. For a class of observables with matrix-valued Weyl symbols\nproportional to the identity matrix, the Weyl-Wigner-Moyal formalism is\nproposed. The evolution equations are found to coincide with their counterparts\nin relativistic quantum mechanics with non-local Hamiltonian. The difference\nbetween the theories is connected with peculiarities of the constraints on the\ninitial conditions. Effective increase in coherence between eigenstates of the\nHamiltonian is found. Relativistic coherent states that take into account a\nnon-trivial charge structure of the position and momentum operators and satisfy\nthe charge superselection rule are considered. On this basis, the entangled\ncoherent states are developed.",
