A-twisted Landau-Ginzburg模型

A-twisted Landau-Ginzburg models

Josh Guffin, Eric Sharpe

摘要:

本文讨论了一类A-扭曲Landau-Ginzburg模型中的关联函数。虽然B-扭曲的朗道-金兹伯格模型已经在文献中得到了广泛的讨论,但实际上还没有关于A-扭曲理论的工作。特别是,我们研究的例子Landau-Ginzburg模型的拓扑非平凡的空间-不只是向量空间-远离大半径的限制,所以人们期望非平凡的曲线校正。通过研究与非平凡Calabi-Yaus上的非线性西格玛模型具有相同普适性类的Landau-Ginzburg模型的例子,我们得到了我们方法的非平凡检验以及虚拟基本类计算的一些简单例子的物理实现.

英文摘要:

In this paper we discuss correlation functions in certain A-twisted Landau-Ginzburg models. Although B-twisted Landau-Ginzburg models have been discussed extensively in the literature, virtually no work has been done on A-twisted theories. In particular, we study examples of Landau-Ginzburg models over topologically nontrivial spaces - not just vector spaces - away from large-radius limits, so that one expects nontrivial curve corrections. By studying examples of Landau-Ginzburg models in the same universality class as nonlinear sigma models on nontrivial Calabi-Yaus, we obtain nontrivial tests of our methods as well as a physical realization of some simple examples of virtual fundamental class computations.
