某些纤维制品曲线的Landau-Ginzburg模型

Landau-Ginzburg models for certain fiber products with curves

Zhuo Chen, Tony Pantev, Eric Sharpe

摘要:

在本文中,我们描述了一个家庭的非紧的Kahler三重的平凡正则丛混合Landau-Ginzburg模型的物理实现,由一些最近的非Kahler解决方案的Strominger系统的动机,并利用一些最近的想法从GLSM。我们考虑了作为紧亏格g黎曼曲面和非紧三重曲面的纤维积的三重曲面。每个亏格g黎曼曲面都是用最近的GLSM技巧构造的,作为在2g + 2次轨迹上分支的P^1的双覆盖,通过非微扰效应实现,而不是作为超势的临界轨迹。我们特别关注与某些超Kahler四维流形的Kahler扭量空间集合相对应的特殊情况,特别是R^4、C^2/Z_k和S^1 x R^3的扭量空间。我们检查在所有情况下,平凡规范丛产生的条件物理匹配的数学约束。

英文摘要:

In this paper we describe a physical realization of a family of non-compact Kahler threefolds with trivial canonical bundle in hybrid Landau-Ginzburg models, motivated by some recent non-Kahler solutions of Strominger systems, and utilizing some recent ideas from GLSMs. We consider threefolds given as fiber products of compact genus g Riemann surfaces and noncompact threefolds. Each genus g Riemann surface is constructed using recent GLSM tricks, as a double cover of P^1 branched over a degree 2g + 2 locus, realized via nonperturbative effects rather than as the critical locus of a superpotential. We focus in particular on special cases corresponding to a set of Kahler twistor spaces of certain hyperKahler four-manifolds, specifically the twistor spaces of R^4, C^2/Z_k, and S^1 x R^3. We check in all cases that the condition for trivial canonical bundle arising physically matches the mathematical constraint.
