Let A be a sign pattern matrix of order n.If every monic real polynomial of degree n can be achieved as the characteristic polynomial of some matrix B∈Q(A),then the sign pattern A of order n is a spectrally arbitrary pattern.A sign pattern A is minimally spectrally arbitrary if it is spectrally arbitrary but is not spectrally arbitrary if any nonzero entry(or entries) of A is replaced by zero.In this paper,we introduce a new class of minimally spectrally arbitrary sign patterns for all orders n≥7. |
