Minimal algebraic complexes over $D_{4n}$

Wajid H Mannan and Seamus O’Shea

Algebraic & Geometric Topology 13 (2013) 3287–3304
Abstract

We show that cancellation of free modules holds in the stable class Ω3() over dihedral groups of order 4n. In light of a recent result on realizing k–invariants for these groups, this completes the proof that all dihedral groups satisfy the D(2) property.
