Let A be an M-matrix in standard lower block triangular form, with diagonal blocks Ai; irreducible. Let S be the set of indices a such that the diagonal block A"" is singular. We define the singular graph of A to be the set S with partial order defined by a > (3 if there exists a chain of non-zero blocks A,,;, A;i' .. . , AIi3" Let Al be the set of maximal elements of S, and define the p-th lev...
