摘要

Nonequilibrium dynamics has recently become a very active field of research in particle theory, in cosmology, and in solid state physics. The typical systems under investigation consist of a classical field that drives the nonequilibrium evolution and quantum or thermal fluctuations. The systems display particle production, the back reaction of these particles to the classical field is included in one-loop, large-N or Hartree approximation. The models considered up to now include scalar or fermionic fluctuations. In the cosmological context nonabelian gauge theories are also of interest. So the formalism should be developed to include gauge filed fluctuations.
