在这篇文章中，我们将概述M理论三形式势的离散挠率模拟的推导。我们发现，C域上的轨道群作用量之间的某些差异可以用H ^3（G，U（1））来分类。我们还计算了薄膜对T^3的低能有效作用在扭曲扇形的模拟中所看到的相位，并注意到它们在明显的SL（3，Z）作用下是不变的。
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 H^3(G, U(1)). We also compute the phases that the low-energy effective action of a membrane on T^3 would see in the analogue of a twisted sector, and note that they are invariant under the obvious SL(3,Z) action.
