Derivations,triple Derivations And Automorphism Groups Of Six-dimensional Nilpotent Lie Algebras

In the paper we describe derivations,triple derivations and automorphism groups of 26 serious of six-dimensional nilpotent Lie algebras by use of classifica-tion of six-dimensional nilpotent Lie algebras over the closed fields of characteristic different from 2.In section 1,derivations of six-dimensional nilpotent Lie algebras are determined using the definition of derivations.In section 2,triple derivations of six-dimensional nilpotent Lie algebras are determined using the definition of triple derivations.In section 3,automorphism groups of six-dimensional nilpotent Lie algebras are determined using the definition of automorphisms.
