Quotients of maximal class of thin Lie algebras. The odd characteristic case

Among thin graded Lie algebras, which are particular instances of Lie algeb ras of finite width, there are many interesting objects, such as the graded Lie algebra associated to the Nottingham group. Among the factors of a thi n algebra with respect to the terms of the lower central series, there is a greatest factor which is of maximal class. In thin Lie algebras associated to groups, this factor is metabelian. In this paper we show that the same holds in general, provided the characte ristic of the underlying field is odd. In another paper by the second autho r it is shown that this is not the case for characteristic two.
