构造了一般的自旋膜束缚态，沿着它们的近视界极限作为非对易场论的对偶描述。对于具有B场的自旋D膜世界体积理论，给出了规范耦合相结构的一般分析，表现出各种新的特征，已经在零角动量的水平上。我们证明了热力学等价于大N时的交换情形，并讨论了有限N的可能性和结果。作为一般分析的一个应用，讨论了NCSYM热力学的适用范围。鉴于最近证实的7维NCSYM的存在性，详细地介绍了自旋D 6膜理论的热力学，并找到了一个稳定的区域。对自旋的M5-M2膜束缚态也给出了相应的结果，包括近视界极限和热力学。
General spinning brane bound states are constructed, along with their near-horizon limits which are relevant as dual descriptions of non-commutative field theories. For the spinning D-brane world volume theories with a B-field a general analysis of the gauge coupling phase structure is given, exhibiting various novel features, already at the level of zero angular momenta. We show that the thermodynamics is equivalent to the commutative case at large N and we discuss the possibility and consequences of finite N. As an application of the general analysis, the range of validity of the thermodynamics for the NCSYM is discussed. In view of the recently conjectured existence of a 7-dimensional NCSYM, the thermodynamics of the spinning D6-brane theory, for which a stable region can be found, is presented in detail. Corresponding results for the spinning M5-M2 brane bound state, including the near-horizon limit and thermodynamics, are given as well.
