- 1.The subject matter discussed here is considered in greater detail in two forthcoming papers, “Entropy Generation in Cosmological Particle Creation,” by B. L. Hu, H. E. Kandrup, and D. Pavon, and “Non-equilibrium Entropy in Classical and Quantum Field Theory,” by H. E. Kandrup.Google Scholar
- 3.Earlier work on this subject is summarized, e.g., by B. L. Hu in L. Z. Fang and R. Ruffini (eds.),“Cosmology of the Early Universe,” (World Science, 1984).Google Scholar
- 4.This net increase is a very general result. A proof for a slightly different Hamiltonian is provided by H. E. Kandrup, Class. and Quantum Grav. Lett. (in press).Google Scholar
