Abstract

We investigate the triple derivation algebras of Lie algebras. It is proved that, if the base ring contains , L is a perfect Lie algebra with zero center, then every triple derivation of L is a derivation, and every triple derivation of the derivation algebra Der(L) is an inner derivation.
