A reconstruction method for anisotropic universes in unimodular F(R)-gravity

Abstract An extension of unimodular Einsteinian gravity in the context of F(R) gravities is used to construct a class of anisotropic evolution scenarios. In unimodular GR the determinant of the metric is constrained to be a fixed number or a function. However, the metric of a generic anisotropic uni...
