Derivations and automorphisms of free nilpotent Lie algebras and their quotiens
Get PDFLet \n_{d,t} be the free nilpotent Lie algebra of type and nilindex
. Starting out with the derivation algebra and the automorphism group of
\n_{d,t}, we get a natural description of derivations and automorphisms of
any generic nilpotent Lie algebra of the same type and nilindex. Moreover,
along the paper we discuss several examples to illustrate the obtained results.Comment: 13 page
