Outline of Final Research Achievements

The problem of real-time evolution with quantum fluctuations has universal relevance for establishing descriptions for realistic physics phenomena. This is a very important problem, and nevertheless, no general and nonperturbative algorithm at work is known, especially for relativistic quantum field theory. For the purpose to attack this problem, we investigated the sign problem, fixed point structures of the Boltzmann equation, particle production calculations, transport coefficient estimations including resummed diagrams. In this way we took the approaches from various perspectives, to find concrete answers for respective problems.
