%0 Journal Article %A Campoamor-Stursberg, Rutwig %A Ancochea Bermúdez, José María %T On 2-abelian (n-5)-filiform Lie algebras %D 2001 %@ 0092-7872 %U https://hdl.handle.net/20.500.14352/57186 %X We classify the (n − 5)-filiform Lie algebras which have the additional property of a non-abelian derived subalgebra. Moreover we show that if a (n − 5)-filiform Lie algebra is characteristically nilpotent, then it must be 2-abelian. %~
