Quillen's plus construction and the D(2) problem

W H Mannan

Algebraic & Geometric Topology 9 (2009) 1399–1411

DOI: 10.2140/agt.2009.9.1399
Abstract

Given a finite connected 3–complex with cohomological dimension 2, we show it may be constructed up to homotopy by applying the Quillen plus construction to the Cayley complex of a finite group presentation. This reduces the D(2) problem to a question about perfect normal subgroups.
