“…A systematic study of algebraic properties of Leibniz algebras is started from the Loday paper. So, several classical theorems from Lie algebras theory have been extended to the Leibniz algebras case; many classification results regarding nilpotent, solvable, simple, and semisimple Leibniz algebras are obtained (see, for example, [4,7,14,32,33,40,44,47,50] and references therein). Leibniz algebras is a particular case of terminal algebras and, on the other hand, symmetric Leibniz algebras are Poisson admissible algebras.…”
