二部场论是一类新的四维N=1量子场论,由有边黎曼曲面上的二部图定义。本文纯粹利用规范理论,导出了图中平方移动下面权的聚类变换。在这种情况下,我们通过连接相关bft的主空间的正则参数化来获得它们。对于圆盘上的bft,这些变换遵循格拉斯曼坐标系的性质。这代表了Grassmannian组合对象列表的新添加,例如匹配和矩阵多面体,已被证明是从BFT动力学中出现的。
Bipartite field theories (BFTs) are a new class of 4D N=1 quantum field theories defined by bipartite graphs on bordered Riemann surfaces. In this paper we derive, purely in terms of the gauge theory, the cluster transformations of face weights under square moves in the graph. In this context, we obtain them by connecting regular parametrizations of the master space of the associated BFTs. For BFTs on a disk, these transformations follow from the properties of coordinates in the Grassmannian. This represents a new addition to the list of combinatorial objects for the Grassmannian, such as matching and matroid polytopes, that have been shown to emerge from BFT dynamics.
