Abstract :
In this paper we study the impact of Minkowski metric matrix on a projection in theMinkowski Space M along with their basic algebraic and geometric properties.The relationbetween the m-projections and the Minkowski inverse of a matrix A in the minkowski space Mis derived. In the remaining portion commutativity of Minkowski inverse in Minkowski SpaceM is analyzed in terms of m-projections as an analogous development and extension of theresults on EP matrices.
