In this paper, we obtain some estimates for the Ξ³ -diagonally and product Ξ³ -diagonally dominant degree of the Schur complement of matrices. As application we present some bounds for the eigenvalues of Schur complement by the entries of the original matrix. Based on these results, we give a kind of
