Query: Bogomolov multiplier and the Lazard correspondence   In this paper we extend the notion of CP covers for groups to the field of
Lie algebras, and show that despite the case of groups, all CP covers of a Lie
algebra are isomorphic. Finally we show that CP covers of groups and Lie rings
which are in Lazard correspondence, are in Lazard correspondence too, and the
Bogomolov multipliers are isomorphic.
