Orientifolds的T-对偶与扭KR-理论

T-duality For Orientifolds and Twisted KR-theory

Charles Doran, Stefan Mendez-Diez, Jonathan Rosenberg

摘要:

定向折叠弦论中的D-膜荷是由Atiyah的KR-理论分类的。然而,这是假设所有O平面具有相同的符号。当有不同符号的O平面时,物理学需要一个“具有符号选择的KR理论”,直到现在还没有被数学家研究过(除了Moutuou,他没有想到具体的应用)。我们给出了这个理论的定义,并计算它的orientifold理论紧的圆和2-环面。我们还解释了如何以及为什么实施额外的“扭曲”。我们证明了我们的结果满足椭圆曲线上定向折叠弦论的所有可能的T-对偶关系,这将在后续工作中进一步研究。

英文摘要:

D-brane charges in orientifold string theories are classified by the KR-theory of Atiyah. However, this is assuming that all O-planes have the same sign. When there are O-planes of different signs, physics demands a "KR-theory with a sign choice" which up until now has not been studied by mathematicians (with the unique exception of Moutuou, who didn't have a specific application in mind). We give a definition of this theory and compute it for orientifold theories compactified on a circle and 2-torus. We also explain how and why additional "twisting" is implemented. We show that our results satisfy all possible T-duality relationships for orientifold string theories on elliptic curves, which will be studied further in subsequent work.
