本文在平坦(2n + 1)维欧氏空间中猜想一个嵌入算子,它赋予任意2n + 1个埃尔米特矩阵一个2n维超曲面。这相当于精确定义了一个对应于N个D 0-膜的模糊D(2n)-膜。突现超曲面上的点对应于嵌入算符的零本征态,这可以解释为突现非对易几何中的相干态。利用这个对应关系,可以计算出D(2n)-膜的所有物理性质。我们应用我们的猜想,非交换平坦和球形空间。作为副产品,我们得到了一个结构的旋转对称平坦的非交换空间在4维。
A bstractWe conjecture an embedding operator which assigns, to any 2n + 1 hermitian matrices, a 2n-dimensional hypersurface in flat (2n + 1)-dimensional Euclidean space. This corresponds to precisely defining a fuzzy D(2n)-brane corresponding to N D0-branes. Points on the emergent hypersurface correspond to zero eigenstates of the embedding operator, which have an interpretation as coherent states underlying the emergent noncommutative geometry. Using this correspondence, all physical properties of the emergent D(2n)-brane can be computed. We apply our conjecture to noncommutative flat and spherical spaces. As a by-product, we obtain a construction of a rotationally symmetric flat noncommutative space in 4 dimensions.
