| Abstract: | In this paper,we introduce the notion of the fixed point of ring automorphism,make preliminary research about properties and existence of the fixed point of ring automorphism,and obtain some properties of fixed point of ring automorphism and some equivalent conditions of existence of non-zero fixed point of ring automorphism.By the fixed point of ring automorphism we characterize the structure of ring. |
