论文摘要
我们研究了与纯量规紧凑型扁平量规场选择相关的全球拓扑数据的作用。我们的研究始于紧凑型扁平歧管上的扰动弦线紧凑，可在5个维度中保留8个增压。通过在杂种字符串中为威尔逊线和b-field gerbe在II型字符串中包含非平凡的载体，我们找到了将这些背景与其他字符串压实相关联的世界表二重性。尽管我们的简单示例允许进行明确的分析，但这些概念和一些方法扩展到更广泛的压缩类别，并对字符串二元性具有影响，扰动性和其他方式。
We examine the role of global topological data associated to choices of holonomy for flat gauge fields in string compactification. Our study begins with perturbative string compactification on compact flat manifolds preserving 8 supercharges in 5 dimensions. By including non-trivial holonomy for Wilson lines in the heterotic string and for the B-field gerbe in the type II string we find worldsheet dualities that relate these backgrounds to other string compactifications. While our simple examples allow for explicit analysis, the concepts and some of the methods extend to a broader class of compactifications and have implications for string dualities, perturbative and otherwise.
