我们研究了最大超对称pp波背景下的闭式和开放式超膜。在膜理论的框架下，利用狄拉克括号计算了超代数，并利用表面项得到了它的中心扩张。这一结果支持了pp波极限中膜理论中延拓物体的存在。当去掉中心项时，相关代数与Berenstein-Maldacena-Nastase矩阵模型完全一致。我们还讨论了pp波上的开放超膜，并阐述了可能的边界条件。
We study the closed and open supermembranes on the maximally supersymmetric pp-wave background. In the framework of the membrane theory, the superalgebra is calculated by using the Dirac bracket and we obtain its central extension by surface terms. The result supports the existence of the extended objects in the membrane theory in the pp-wave limit. When the central terms are discarded, the associated algebra completely agrees with that of Berenstein–Maldacena–Nastase matrix model. We also discuss the open supermembranes on the pp-wave and elaborate the possible boundary conditions.
