From author's summary: A general method for incomplete factorization of M-matrices in block-matrix form is presented. The method generalizes previous methods for pointwise incomplete factorization as well as a method for tridiagonal block matrices. Also a new and more general result is presented on the existence of so-called modified incomplete factorization which satisfy a generalized rowsum criterion.
