Abstract

We study complex projective varieties that parametrize (finite-dimensional) filiform Lie algebras over C, using equations derived by Millionshchikov. In the infinite-dimensional case we concentrate our attention on N-graded Lie algebras of maximal class. As shown by A. Fialowski there are only three isomorphism types of N-graded Lie algebras L = ⊕i=l Li of maximal class generated by Li and L2L = (L1, L2). Vergne described the structure of these algebras with the property L = (L1). In this paper we study those generated by the first and q-th components where q > 2, L = (Ll, Lq). Under some technical condition, there can only be one isomorphism type of such algebras. For q = 3 we fully classify them. This gives a partial answer to a question posed by Millionshchikov.
