摘要
The ideal-relation graph over a ring R, written as Gamma(i) (R), is a directed graph which has R as vertex set and there is a directed edge from a vertex x to a distinct vertex y if and only if the (two-sided) ideal of R generated by x is properly contained in the ideal generated by y. In this paper, the automorphisms of Gamma(i) (R) are characterized when R is the ring of all n x n upper triangular matrices over a finite field.
