  • 1. Theory Group, Department of Physics, University of Texas, Austin, Texas, 78712 (United States)

Description

It is shown that the generating function for tree graphs in the ''in-in'' formalism may be calculated by solving the classical equations of motion subject to certain constraints. This theorem is illustrated by application to the evolution of a single inflaton field in a Robertson-Walker background.
