m-Projections involving Minkowski inverse and Range Symmetric property in Minkowski Space

In this paper we study the impact of Minkowski metric matrix on a projec- tion in the Minkowski Space M along with their basic algebraic and geometric proper- ties.The relation between the m-projections and the Minkowski inverse of a matrix A in the minkowski spaceMis derived. In the remaining portion commutativity of Minkowski inverse in Minkowski Space M is analyzed in terms of m-projections as an analogous development and extension of the results on EP matrices.
