Pseudo-complex General Relativity and neutron stars

The pseudo‐complex General Relativity, which includes a minimal length, is resumed and similarities to other theories are pointed out. For a zero minimal length the theory exhibits a remnant contribution, which is associated to a dark energy. It suggests the principle that a mass not only curves the space around it but also changes the vacuum properties, which in turn affect the metric. Some experimental predictions are shortly mentioned. The consequences of the presence of a dark energy are investigated for the case of neutron stars. It is shown that large masses of neutron stars are possible. (© 2014 WILEY‐VCH Verlag GmbH & Co.
