Abstract: Zhao and Zhu proved the following result: Every matrix in upper triangular matrix algebras over the complex number field is a Jordan all-derivable point. The aim of this paper is to show that every matrix in upper triangular matrix algebras over an infinite field of characteristic not 2 is a Jordan all-derivable point.

Key words: Jordan all-derivable point;derivation;upper triangular matrix algebra, triangular algebra
