我们表明,给定三个埃尔米特矩阵,人们可以称之为膜的模糊表示,有一个定义明确的过程来定义一组嵌入在R^3 $中的定向黎曼曲面,使用定义为R^3 $中的点的索引函数,该索引函数是从三个矩阵和点构造的。曲面的集合在旋转、平移和平移操作下是协变的,它在直和上是可加的,并且曲面的方向被矩阵的复共轭反转。我们建立的指数与Hanany-Witten效应密切相关。我们还表明,表面携带的信息的线丛与他们的联系。 我们讨论这些想法的全息矩阵模型和黑洞动力学的研究中的应用。
We show that given three hermitian matrices, what one could call a fuzzy representation of a membrane, there is a well defined procedure to define a set of oriented Riemann surfaces embedded in $R^3$ using an index function defined for points in $R^3$ that is constructed from the three matrices and the point. The set of surfaces is covariant under rotations, dilatations and translation operations on $R^3$, it is additive on direct sums and the orientation of the surfaces is reversed by complex conjugation of the matrices. The index we build is closely related to the Hanany-Witten effect. We also show that the surfaces carry information of a line bundle with connection on them. We discuss applications of these ideas to the study of holographic matrix models and black hole dynamics.
