Suppose R is a ring with 1 and C a central subring of R. Let T,(R) be the C-algebra of upper triangular n x n matrices over R. Recently several authors have shown that if R is sufficiently well behaved, then every C-automorphism of T,,(R) is the composites of an inner automorphism and an automorphis
