Nahm方程的一个推广最近被Basu和Harvey猜想为描述在M5膜上结束的一堆M2膜的束缚状态的BPS条件。本文从M2膜世界体积动力学的观点出发，给出了所提出的BPS方程的精确解，并给出了M2膜在两个M5膜之间伸展的边界条件。不幸的是，由于多个M5膜或多个重合的M2膜的作用尚不清楚，人们只能求助于对该提议的一致性检查，而不是直接比较M2和M5的世界体积观点。我们的解的存在应该被看作是对猜想的这种一致性检验，也是对多个M2和M5膜动力学的新的洞察的来源。
A generalization of Nahm's equation has been recently conjectured by Basu and Harvey to be the BPS condition describing the bound state of a stack of M2-branes ending on an M5-brane. In this note exact solutions are presented for the proposed BPS equation — which is from the point of view of the M2-brane world-volume dynamics — with boundary conditions appropriate for M2-branes stretching between two M5-branes. Unfortunately, since the action for multiple M5-branes or for multiple coincident M2-branes is not known, one can only resort to consistency checks of the proposal instead of a direct comparison of the M2 and M5 world-volume point of views. The existence of our solutions should be seen as such a consistency check of the conjecture, and also as a source of new insight into the dynamics of multiple M2 and M5-branes.
