✦ Synopsis

The temperature evolution law is determined for an expanding FRW type Universe with a mixture of matter and radiation Ž . where 'adiabatic' creation of photons has taken place. The influence of the radiation specific entropy per particle on the physical conditions for having a hot big-bang Universe with photon creation is examined in detail and compared to the standard FRW results. Some additional physical consequences are discussed in the context of the simplest big-bang cosmology with 'adiabatic' photon creation.
