Let R be a commutative ring with unity. The unit graph G(R) is defined such that the vertex set of G(R) is the set of all elements of R, and two distinct vertices are adjacent if their sum is a unit in R. In this paper, we show that for each prime, p,G(Zp) and G(Z2p) are eigensharp graphs. Likewise, we show that the unit graph associated with the ring Zp[x]∕x2 is an eigensharp graph.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
