摘要:

我们提出了一个详细的研究D膜超势依赖于几个开弦和闭弦变形。与膜相关的相对上同调群定义了一个广义超几何GKZ系统,它决定了离壳超势及其变形下的解析性质。对于一系列多参数的例子,得到了II/F型理论紧化的N=1超势的显式表达式。使用霍奇理论方法开弦镜像对称性,我们得到新的预测积分盘不变量的A模型的瞬子扩展。我们研究了膜真空在不同卡-丘空间之间的极值跃迁下的行为,并观察到卡-丘真空的网络对于一类特殊的膜仍然是连通的。

英文摘要:

We present a detailed study of D-brane superpotentials depending on several open and closed-string deformations. The relative cohomology group associated with the brane defines a generalized hypergeometric GKZ system which determines the off-shell superpotential and its analytic properties under deformation. Explicit expressions for the N=1 superpotential for families of type II/F-theory compactifications are obtained for a list of multi-parameter examples. Using the Hodge theoretic approach to open-string mirror symmetry, we obtain new predictions for integral disc invariants in the A model instanton expansion. We study the behavior of the brane vacua under extremal transitions between different Calabi-Yau spaces and observe that the web of Calabi-Yau vacua remains connected for a particular class of branes.
