For a commutative semiring R with non-zero identity, the maximal graph of R , denoted by M G ( R ) , is the graph whose vertices are all elements of U M ( R ) with two distinct vertices joined by an edge when there is a maximal co-ideal that contains both of them. In this paper, we study some properties of maximal graph such as planarity, radius, splitting and domination number.
