Abstract:
We consider the ‘`inclusive" {(}"partial"{\rm)} method for describing
nonequilibrium dissipative systems at the early {\rm(}kinetic{\rm)} evolution
stage, when the temperature distribution is nonuniform. We formulate
the perturbation theory in terms of space–time-local temperature Green’s
functions and derive the Liouville equation for the one-particle partition
function.
Keywords:
real-time finite-temperature field theory, perturbation theory.
