Background

This conjecture (adapted from Benson and Greenlees’ Conjecture 1.7 for finite groups) proposes that the bounded derived category of cochains on BG is generated by the cochains on a maximal torus BT.

The paper proves that this conjecture is equivalent to the conjecture about generation by objects of the form Hom_{C_G}(k, X). It also shows the conjecture holds under the hypothesis that Db(C^(BG)) is generated by formal modules.
