环面簇上同调的计算工具

Computational Tools for Cohomology of Toric Varieties

Ralph Blumenhagen, Benjamin Jurke, Thorsten Rahn

摘要:

在这篇综述中,新的非标准技术的计算上同调类环面品种进行了总结。在介绍复曲面几何的基本定义和性质之后,讨论了确定复曲面簇上的线丛值上同调群维数的一个具体计算算法.手征无质量物质谱的计算弦紧化的应用进行了讨论,并使用软件包cohomCalg,其效用是突出了一个新的目标空间对偶对(0,2)杂种优势弦模型。

英文摘要:

In this review, novel non-standard techniques for the computation of cohomology classes on toric varieties are summarized. After an introduction of the basic definitions and properties of toric geometry, we discuss a specific computational algorithm for the determination of the dimension of line-bundle valued cohomology groups on toric varieties. Applications to the computation of chiral massless matter spectra in string compactifications are discussed and, using the software package cohomCalg, its utility is highlighted on a new target space dual pair of (0,2) heterotic string models.
