Necessary and sufficient conditions for the product of range symmetric matrices of rank r to be range symmetric in Minkowski space M is derived. Also equivalent conditions for the product of two range symmetric block matrices to be range symmetric are established. As an application we have shown that a block matrix in Minkowski space can be expressed as a product of range symmetric matrices in M. 2000 Mathematics Subject Classification: Primary 15A57, Secondary 15A09.
