We generalize our approach to solving the Friedmann equation by including further energy contributions, in addition to that of matter, to allow greater freedom in fitting the model parameters to the observational results. This results in a variety of further solutions, some of which we derive and discuss in detail. In addition, we also address the connection with observational results and general physical considerations.

摘要

We generalize our approach to solving the Friedmann equation by including further energy contributions, in addition to that of matter, to allow greater freedom in fitting the model parameters to the observational results. This results in a variety of further solutions, some of which we derive and discuss in detail. In addition, we also address the connection with observational results and general physical considerations.
