Abstract

We are going to elaborate new one-loop effective action method (in-in EA) for strong-field quantum field theory in the Friedmann- Robertson-Walker universe. Such an action is useful to study the vacuum instability in the background under consideration. The method will be applied also to many different strong-field QED problems and to study of phase transitions in early Universe. (AU)
