MATRICES OVER RINGS
Aiat Hadj Ahmed Driss (Maroc) and Ben Yakoub L’Moufadal (Maroc)

Abstract: Let R be a ring with
identity. Denote by tn
+ 1(R)
the ring of upper triangular n
+ 1 by n
+ 1 matrices over R. In this note we give an
explicit description of the Lie derivations of tn
+ 1(R). |
Keywords and phrases: upper triangular
matrices, Lie derivations, derivations. |
