Abstract
Let R be a commutative ring with nonzero identity. Then the Jacobson graph of R, denoted by JR, is defined as a graph with vertex set R\\J(R) such that two distinct vertices x and y are adjacent if and only if 1 − xy is not a unit of R. We obtain some graph theoretical properties of JR including its connectivity, planarity and perfectness and we compute some of its numerical invariants, namely diameter, girth, dominating number, independence number and vertex chromatic number and give an estimate for its edge chromatic number.
