| 摘 要： | 1. IntroductionJohnson in 1] gave an overview about inverse M-matriX problems and proved that ifB is a power invaxiant zero pattern matrix, then there is a positive diagonal matriX D suchthat B D is an inverse M-matrix. He also put several open problems such asQuestion. Consider B 6 N such that al B has power invariat zero pattern fora > 0, where N denotes the set of n x n nonnegative matrices, I is the n x n idelltity madrid.How mad ac) a fUnction of B, be charajcterized such that…
