论文摘要
我们确定了所有六维小弦理论（LST）的2组结构常数，该理论在没有冷冻奇点的情况下进行了几何设计。我们将此结果用作T偶性检查的一致性检查：一对T偶LST的两组必须匹配。当t偶数涉及离散对称性扭曲时，匹配中使用的2组被修改。我们在几个示例中演示了2组的匹配。
We determine the 2-group structure constants for all the six-dimensional little string theories (LSTs) geometrically engineered in F-theory without frozen singularities. We use this result as a consistency check for T-duality: the 2- groups of a pair of T-dual LSTs have to match. When the T-duality involves a discrete symmetry twist the 2-group used in the matching is modified. We demonstrate the matching of the 2-groups in several examples.
