Abstract
We derive the classical transport equation, in scaler held theory with
a g(2)V(phi) interaction, from the equation of motion for the quantum
field. We obtain a very simple, but iterative, expression for the eff
ective action Gamma which generates all the n-point Green functions in
the high-temperature limit. An explicit and closed form is given for
Gamma in the static case.
