摘要:
AbstractPhenomenological models of cosmic phase transitions are presented. We consider phase transitions (i) with fixed initial and final states or (ii) in the relaxation time approximation. The Friedmann equations are solved and the entropy production due to the non‐equilibnum transition is calculated for a bag model equation of state. Numerical examples are given for the confinement transition, but the formulae presented apply directly to the GUT transition, to
