- Descrição
- In this paper the relationship between the different temperatures present in a radiative plasma is examined. In particular, the physical and the operational meaning of Eckart's temperature is discussed. An entropy density formula for the radiative component and its fractional variation rate are derived. We have also suggested a reformulation of Weinberg's conditions for maximum entropy production. The effect of radiative bulk viscosity in diluting monopoles in the very early universe is estimated.
