Entropy from Extra Dimensions

Abstract

The phenomenon of "dynamical compactification" in a universe with $4 + n_{c}$ dimensions is studied, and it is found that if the whole process is adiabatic, entropy is pumped into the effective four-dimensional universe. Some cosmological consequences of this fact are discussed.
