Activities reported include: work on lattice gauge theory, particularly the construction of a fast parallel computer for Monte Carlo simulation of the lattice version of quantum chromodynamics; decoupling of heavy fermions which are involved in anomaly cancellation; U(1)-vector current in the presence of arbitrary left and right chiral gauge fields and an arbitrary Higgs field evaluated in the long-distance approximation; obtaining the Schroedinger equation for a spin-0 particle in the field of a dyon by dimensional reduction from the four-dimensional harmonic oscillator; investigation of some consequences for physical processes of a discrete structure for space-time; work on the effect of retardation on Casimir forces in Rydberg atoms; calculations of the retarded interaction due to two-photon exchange between objects of arbitrary shape; study of gravity on a lattice; difference equations as the basis of fundamental physical theories; Feynman rules in curved space; Hawking radiation from a black hole; theory of lattice QCD and on Monte Carlo algorithms; perturbative QCD and its applications to high energy reactions; development of a formalism which would allow one to systematically add perturbative and non-perturbative contributions in physical processes at high energies without the danger of doubly counting these contributions; calculations of power-suppressed corrections to strong processes; construction of a supercomputer for performing numerical studies of lattice gauge theories and investigation of the thermodynamics of quarks and gluons; and work on problems arising from the application of particle physics to the study of cosmology. 48 refs.
