Abstract
A quantum field theory warm inflation model is presented that solves the ho rizon and flatness problems. The model obtains, from the elementary dynamic s of particle physics, cosmological scale factor trajectories that begin in a radiation dominated regime, enter an inflationary regime, and then smoot hly exit back into a radiation dominated regime, with non-negligible radiat ion throughout the evolution.
