Description
Summary:The Friedmann models of the universe filled with various types of matter are considered. For these models, the cosmological parameters are constructed. Some alternative types of matter with negative pressure are considered instead of cosmological constant. It is shown that the model with dust and domain walls leads to different types of the universe evolution depending on the ratio between constants of the model. The case where the resulting model is consistent with the cosmological observations is represented.
