Abstract
Let R be a commutative ring with non-zero identity and J(R) be the Jacobson radical of R. The Jacobson graph of R denoted by J_R is a graph with vertex-set R\J(R) such that two distinct vertices a and b in R\J(R) are adjacent if and only if 1-ab is not a unit of R. I this talk we characterize all finite commutative rings R such that the Jacobson graph J_R are toroidal.
