Transporting cohomology in Lazard correspondence

Group Theory 2014-05-22 v2

Abstract

Lazard correspondence provides an isomorphism of categories between finitely generated nilpotent pro-pp groups of nilpotency class smaller than pp and finitely generated nilpotent Zp\mathbb{Z}_p-Lie algebras of nilpotency class smaller than pp. Denote by HGriH_{Gr}^i and HLieiH_{Lie}^i the group cohomology functors and the Lie cohomology functors respectively. The aim of this paper is to show that for i=0i=0, 11 and 11, and for a given category of modules the cohomology functors HGriexpH_{Gr}^i\circ \textbf{exp} and HLieiH^i_{Lie} are naturally equivalent. A similar result is proven for i=3i=3 and the relative cohomology groups.
