论文摘要
我们在K3纤维上构建了一种特殊的D4-D2-Brane配置三倍:在K3光纤上的规范D4-branes,以及其基本$ \ Mathbb {p} _1 $上的另一种D2-BRANES,通过在两个维度中使用普通的非线性Sigma模型。我们将得出此结构的$ EXT $组的确切表达。通过使用Gepner模型,我们实现了这种配置的存在的可行性,并获得了更多的Brane系统的捆绑数据。
We construct a special D4-D2-brane configuration on the K3 fibered Calabi-Yau threefolds: canonical D4-branes on K3 fiberations and another D2-branes on its base $\mathbb{P}_1$, by using the ordinary nonlinear sigma model in two dimensions. We would derive the exact expression of $Ext$ groups of this construction. By using the Gepner model, we achieve the feasibility of the existence of such a configuration and get more available sheaf's data of this brane system.
