Calabi-Yau三重上稳定丛的新例子

New Examples of Stable Bundles on Calabi-Yau Threefolds

Bjorn Andreas, Norbert Hoffmann

摘要:

本文利用丛扩张的方法构造了Calabi-Yau三重上的稳定丛。这个构造适用于任何给定的卡-丘三重方程,其中h^{1,1}>1。我们给出了秩为2和秩为4的稳定丛的例子,这些稳定丛是由给定的Calabi-Yau空间的纯几何数据构造的。作为应用,我们发现其中一些束满足杂合弦异常抵消所施加的物理约束。

英文摘要:

In this paper we present a construction of stable bundles on Calabi-Yau threefolds using the method of bundle extensions. This construction applies to any given Calabi-Yau threefold with h^{1,1}>1. We give examples of stable bundles of rank 2 and 4 constructed out of pure geometric data of the given Calabi-Yau space. As an application, we find that some of these bundles satisfy the physical constraint imposed by heterotic string anomaly cancellation.
