The theory of splitting is a useful tool for finding solution of a system of linear equations. Many woks are going on for singular system of linear equations. In this article, we have introduced a new splitting called index-proper nonnegative splitting for singular square matrices. Several convergence and comparison results are also established. We then apply the same theory to double splitting.

Keywords: Drazin inverse; group inverse; non-negativity; Index-proper splitting; convergence theorem; comparison theorem..
