摘要
Let n(D) be the set of n x n upper triangular matrices over a division ring D. We characterize the adjacency preserving bijective maps in both directions on n(D) (n epsilon 3). As applications, we describe the ring semi-automorphisms and the Jordan automorphisms on upper triangular matrices over a simple Artinian ring.
