A matrix A is said to have signed null space provided there exists a set S of sign patterns such that the set of sign patterns of vectors in the null space of รƒ is S for each รƒ โˆˆ Q(A). It is a generalization of a number of important qualitative matrix classes such as L-matrices, S \* -matrices, tota

A square real matrix A is said to have signed d-power, if the sign pattern of the power A d is uniquely determined by the sign pattern of A. A is said to have totally signed powers if A has signed d-powers for all positive integers d. A is said to be d-powerful if all the non-zero terms in the expan
