【 摘 要 】

A theoretical model for hybrid expansion law in a spatially flat Friedmann- Robertson-Walker (FRW) model filled with two interacting perfect fluid is developed. We obtain the behaviour of the energy densities, pressures, and the energy transfer as functions of the cosmological time. This provides a new family of solutions for hybrid expansion law with interacting cosmic fluids.
