Potential eventual positivity of sign patterns with the underlying broom graph

A sign pattern is a matrix whose entries belong to the set {+,−,0}. An n-by-nsign pattern A is said to allow an eventually positive matrix or be potentially eventually positive if there exist at least one real matrix A with the same sign pattern as A and a positive integer k0 such that Ak>0 for a...
