Abstract
We introduce and study γ-realizable sequences. For a finite, simple graph G containing no isolated vertices, I ⊆ V(G) is said to be an inverse dominating set if I dominates all of G and I is contained by the complement of some minimum dominating set D. Define a sequence of positive integers (x1,…, xn) to be γ-realizable if there exists a graph G having exactly n distinct minimum dominating sets D1,… Dn where for each i ∈ {1,… n}, the minimum size of an inverse dominating set in V(G) \Di is equal to xi. In this work, we show which sequences having minimum entry 2 or less are γ-realizable. We then detail a few observations and results arising during our investigations that may prove useful in future research.
