Abstract

Let R R be a commutative finite semiring with nonzero identity and H H be an arbitrary multiplicatively closed subset R R . The generalized identity-summand graph of R R is the (simple) graph G H ( R ) GH(R) with all elements of R R as the vertices, and two distinct vertices x x and y y are adjacent if and only if x + y ∈ H x+y∈H . In this paper, we study some basic properties of G H ( R ) GH(R) . Moreover, we characterize the planarity, chromatic number, clique number and independence number of G H ( R ) GH(R) .
