Abstract

The group structure of certain Cohen groups have recently been determined using delicate calculations involving Fox torus homotopy groups. The Cohen groups were first introduced by F. Cohen to tackle the Barratt conjecture. We hope to further investigate how the recent results on Cohen groups can shed light on the Barratt conjecture as well exponents in the unstable homotopy theory.
