论文摘要
在本文中，我们通过2组具有琐碎的单形式对称组BK来研究三维轨道。这些Orbifolds具有全球两种形式的对称性，因此人们期望它们分解成（相当于）其他三维理论的不相交结合，我们证明了这一点。这些理论可以解释为2个ger上的Sigma模型，其形式结构反映了Orbifold构造的特性。
In this paper we study three-dimensional orbifolds by 2-groups with a trivially-acting one-form symmetry group BK. These orbifolds have a global two-form symmetry, and so one expects that they decompose into (are equivalent to) a disjoint union of other three-dimensional theories, which we demonstrate. These theories can be interpreted as sigma models on 2-gerbes, whose formal structures reflect properties of the orbifold construction.
