Abstract

Let GG be a finite 2-group of maximal nilpotency class, and let BGBG be its classifying space. We prove that iterated Massey products in H(BG;\F2)H^*(BG;\F_2) do characterize the homotopy type of BGBG among 2-complete spaces with the same cohomological structure. As a consequence we get an alternative proof of the modular isomorphism problem for 2-groups of maximal nilpotency class.
