Abstract
In this paper, we study the k th upper bases of primitive non-powerful signed digraphs. A bound on the k th upper bases of all primitive non-powerful signed digraphs is obtained, and the equality case of the bound is characterized. We also show that there exists a “gap” in the k th upper base set of primitive non-powerful signed digraphs.
