Motivated by the Cheung's elaborate work [Linear Multilinear Algebra, 51 (2003),299-310], we investigate the construction of a Lie derivation on a generalized matrix algebra and apply it to give a characterization for such a Lie derivation...

Cheung [Linear Multilinear Algebra, 51 (2003), 299{310] characterized Lie derivations on a triangular algebra. In this talk, we study Lie derivations on a generalized matrix algebra and we and some sucient conditions under which a Lie derivation...

-valued mapping‎. ‎In this talk‎, ‎we are mainly dealing with the study of these problems on some variety of algebras‎, ‎including trivial extensions‎, ‎triangular algebras‎, ‎generalized matrix algebras and $C^*-$algebras...
