Abstract

In this paper, an explicit construction of a countable parafree Lie algebra over Z/2\mathbb Z/2 with nonzero second homology is given. It is also shown that the cohomological dimension of the pronilpotent completion of a free noncyclic finitely generated Lie algebra over Z\mathbb Z is greater than two. Moreover, it is proven that there exists a countable parafree group with nontrivial H2H_2.
