Abstract: Using the general method of Owe Axelsson given in 1986 for incomplete factorization of M‐matrices in block‐matrix form, we give a recursive approach to construct incomplete block‐matrix factorization of M‐matrices by proposing a two‐step iterative… read more here.

Abstract: Let A be a commutative unital complex Banach algebra and let $$GL_n(A)$$GLn(A) be the group of invertible $$n\times n$$n×n matrices with entries in A. In this paper we study the problem of the representation of… read more here.
