Abstract

We explore whether the generalized second law of thermodynamics is fulfilled in the transition from a generic initial Einstein static phase to the inflationary phase, with constant Hubble rate, and from the end of the latter to the conventional thermal radiation dominated era of expansion. As it turns out, the said law is satisfied provided the radiation component does not contribute largely to the total energy of the static phase.<br />Comment: 3 pages, 1 figure. Key words: Early universe; Thermodynamics. Submitted to the Proceedings of "13th Marcel Grossmann Meeting". An extended version was published in Physics Letters B 707 (2012) 8-10
