标题： Flux Quantization on M5-branes

摘要： 我们强调了在M5-膜sigma模型中类似于狄拉克的电荷/通量量子化，需要全局完成场内容的需求，并指出世界体积上的超空间Bianchi恒等式及其超引力背景约束了M5的通量量子化定律是非交换上同调理论的一部分，这个理论在有理数上等价于一个扭曲的形式的上同伦。 为了清楚地突出这一微妙点，我们通过M5“超嵌入”重新推导了世界体积3-通量。 最后，假设通量量子化定律实际上是在上同伦中（“假设H”），我们展示了这如何意味着一般M5世界体积上的Skyrmion型孤子以及异质M理论中“开M5膜”边界上的（阿贝尔）任意子孤子。 显示英文摘要

摘要： We highlight the need for global completion of the field content in the M5-brane sigma-model analogous to Dirac's charge/flux quantization, and we point out that the superspace Bianchi identities on the worldvolume and on its ambient supergravity background constrain the M5's flux-quantization law to be in a non-abelian cohomology theory rationally equivalent to a twisted form of co-Homotopy. In order to clearly bring out this subtle point we give a streamlined re-derivation of the worldvolume 3-flux via M5 "super-embeddings". Finally, assuming the flux-quantization law to actually be in co-Homotopy ("Hypothesis H") we show how this implies Skyrmion-like solitons on general M5-worldvolumes and (abelian) anyonic solitons on the boundaries of "open M5-branes" in heterotic M-theory.
