Let T M-n be the algebra of all n x n upper triangular matrices. We say that phi is an element of L(TMn) is a Jordan derivable mapping at G if phi (ST + TS) = phi(S)T + S phi(T) + phi(T)S + T phi(S) for any S, T is an element of TMn, with ST = G. An element G E TNI is called a Jordan all-derivable point of TMn if every Jordan derivable linear mapping phi at G is a derivation. In this paper, we show that every element in TMn is a Jordan all-derivable point. (C) 2010 Elsevier Inc. All rights reserved.
