Complex degenerate metrics in general relativity: a covariant extension of the Moore–Penrose algorithm
Abstract The Moore–Penrose algorithm provides a generalized notion of an inverse, applicable to degenerate matrices. In this paper, we introduce a covariant extension of the Moore–Penrose method that permits to deal with general relativity involving complex non-invertible metrics. Unlike the standar...
