  • Classical relativistic system of N charges. Hamiltonian description, forms of dynamics, and partition function 
    Duviryak, A.; Nazarenko, A.; Tretyak, V. (Condensed Matter Physics, 2001)
    The procedure of reducing canonical field degrees of freedom for a system of charged particles plus field in the constrained Hamiltonian formalism is elaborated up to the first order in the coupling constant expansion. The ...
  • Isotropic forms of dynamics in the relativistic direct interaction theory 
    Duviryak, A.; Shpytko, V.; Tretyak, V. (Condensed Matter Physics, 1998)
    The Lagrangian relativistic direct interaction theory in the various forms of dynamics is formulated and its connections with the Fokker-type action theory and with the constrained Hamiltonian mechanics are established. The ...
  • Large-j Expansion Method for Two-Body Dirac Equation 
    Duviryak, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2006)
    By using symmetry properties, the two-body Dirac equation in coordinate representation is reduced to the coupled pair of radial second-order differential equations. Then the large-j expansion technique is used to solve a ...
  • Solvable Two-Body Dirac Equation as a Potential Model of Light Mesons 
    Duviryak, A. (Symmetry, Integrability and Geometry: Methods and Applications, 2008)
    The two-body Dirac equation with general local potential is reduced to the pair of ordinary second-order differential equations for radial components of a wave function. The class of linear + Coulomb potentials with ...
