The Robertson-Walker metric in a pseudo-complex general relativity

摘要

We investigate the consequences of the pseudo-complex General Relativity within a pseudo-complexified Robertson-Walker metric. A contribution to the energymomentum tensor arises, which corresponds to a dark energy and may change with the radius of the universe, i.e., time. Only when the Hubble function H does not change in time, the solution is consistent with a constant Λ.
