Landau-Ginzburg骨骼

Landau-Ginzburg skeletons

Ian C. Davenport, Ilarion V. Melnikov

摘要:

我们研究了一类具有(2,2)超对称性和中心荷c < 6的不可分解的二维Landau-Ginzburg理论,目的是将所有这类理论分类到边缘形变。我们的结果包括在以前的分类中被忽略的情况。结果是严格的三个或更少的领域,更普遍的是严格的,如果我们假设一个额外的界限。数值计算表明,我们有c<6的不可分解朗道-金兹伯格族的完备集。这个集合由38个无限家族和418个零星病例的有限列表组成。的基本工具是经典的结果Kreuzer和Skarke准齐次孤立奇点和解决方案,某些可行性整数规划问题。

英文摘要:

We study the class of indecomposable two-dimensional Landau-Ginzburg theories with (2,2) supersymmetry and central charge c < 6 with the aim of classifying all such theories up to marginal deformations. Our results include cases overlooked in previous classifications. The results are rigorous for three or fewer fields and more generally are rigorous if we assume an extra bound. Numerics suggest that we have the complete set of indecomposable Landau-Ginzburg families with c<6. This set consists of 38 infinite families and a finite list of 418 sporadic cases. The basic tools are classic results of Kreuzer and Skarke on quasi-homogeneous isolated singularities and solutions to certain feasibility integer programming problems.
