Abstract
Let Tn+1 (R) be upper natrix algebra of order n + 1 over a 2-torsion free commutative ring R with identity. In this paper, we find an automorphism, which is fixed by all orthogonal idempotents and is not an R-algebra automorphism, of Tn+1 (R). Furthermore we prove that this automorphism is an involutive Jordan automorphism of Tn+1 ( R ).关键词
