Abstract

Let S,KS, K be two subrings of a finite ring RR. Then the generalized non-commuting graph of subrings S,KS, K of RR, denoted by ΓS,K\Gamma_{S, K}, is a simple graph whose vertex set is (SK)(CK(S)CS(K))(S \cup K) \setminus (C_K(S) \cup C_S(K)) and two distinct vertices a,ba, b are adjacent if and only if aSa \in S or bSb \in S and abbaab \neq ba. We determine the diameter, girth and some dominating sets for ΓS,K\Gamma_{S, K}. Some connections between the ΓS,K\Gamma_{S, K} and Pr(S,K)\Pr(S, K) are also obtained. Further, Z\Z-isoclinism between two pairs of finite rings is defined and showed that the generalized non-commuting graphs of two Z\Z-isoclinic pairs are isomorphic under some condition.
