Abstract:

A square real matrix A is called sign stable or qualitatively stable if stability is a property of every matrix having the same sign-pattern negative, zero, positive as A. A combinatorial characterization of this notion, announced earlier by the first author and used by the other authors in an efficient algorithm for testing sign stability, is established here. Author
