有边界1+1维N=2理论的位相

Phases Of N=2 Theories In 1+1 Dimensions With Boundary

Manfred Herbst, Kentaro Hori, David Page

摘要:

本文研究了具有阿贝尔规范群的线性西格玛模型中的B型D膜。最重要的发现是等级限制规则。它对规范群在Chan-Paton因子上的表示进行了分类,它可以用来定义在凯勒模空间的一个区域上连接不同特征的特殊点的D-膜族。作为一个应用,我们发现了一个精确的,透明的关系D膜在各种几何阶段,以及自由orbifold和朗道-金斯堡点。这个结果重现并统一了许多早期关于D-膜范畴等价的数学结果,包括McKay对应和Orlov构造。

英文摘要:

We study B-type D-branes in linear sigma models with Abelian gauge groups. The most important finding is the grade restriction rule. It classifies representations of the gauge group on the Chan-Paton factor, which can be used to define a family of D-branes over a region of the Kähler moduli space that connects special points of different character. As an application, we find a precise, transparent relation between D-branes in various geometric phases as well as free orbifold and Landau-Ginzburg points. The result reproduces and unifies many of the earlier mathematical results on equivalences of D-brane categories, including the McKay correspondence and Orlov's construction.
