Analogues of Discrete Torsion for the M-Theory Three-Form
Abstract
In this article we shall outline a derivation of the analogue of discrete torsion for the M-theory three-form potential. We find that some of the differences between orbifold group actions on the C field are classified by H3(G, U(1)). We also compute the phases that the low-energy effective action of a membrane on T3 would see in the analogue of a twisted sector, and note that they are invariant under the obvious SL(3,Z) action.
