In this paper we determine the automorphism group of Cayley graph over the group where p ¹ q are prime numbers, by building the corresponding Schur ring which is generated by Q , and determine the automorphism group of this ring which is the automorphism group of this graph.
The objective of this studying is the important answer on the following open question : Let G and G' be two fuzzy groups and L(G), L(G') be lattices for them, respectively,
We have shown that this statement don’t true in the case general, and we sup
pose some certain conditions on the purposed groups to be the statement holds. Moreover, some important theorems are proved
