Abstract
Abstract Let R be a c ommutative ring with a non-zero identity and J R be its Jacobson graph. We show that if R and R are fi nite commutative rings, then J R ∼= J R if and only if |J (R)|=|J (R)| and R/J (R) ∼= R/J (R). Also, for a Jacobson graph J R , we obtain the structure o f g roup Aut (J R ) of all a utomorphisms o f J R and p rove that under some conditions two semi-simple rings R and R are isomorphic if a nd only if Aut (J R ) ∼= Aut (J R ).
