We introduce some new algebraic and topological properties of the Minkowski inverse of an arbitrary matrix (including singular and rectangular) in a Minkowski space . Furthermore, we show that the Minkowski inverse in a Minkowski space and the Moore-Penrose inverse in a Hilbert space are different in many properties such as the existence, continuity, norm, and SVD. New conditions of the Minkowski inverse are also given. These conditions are related to the existence, continuity, and reverse order law. Finally, a new representation of the Minkowski inverse is also derived.
