紧致Calabi-Yau超曲面的相对周期与开弦整数不变量

Relative periods and open-string integer invariants for a compact Calabi-Yau hypersurface

Hans Jockers, Masoud Soroush

摘要:

在这项工作中,我们计算相对周期的B-膜,实现在一个紧凑的卡-丘超曲面的因子,通过直接积分。虽然我们将直接积分的方法推广到特定的卡-丘几何中,但该方法也自动推广到其他卡-丘几何中的因子。从计算的相对周期,我们提取双对数周期。这些周期有资格描述磁盘瞬子产生的N=1超势的相应的紧凑的镜像卡-丘几何在大体积制度。最后,我们提取整数不变量编码在这些膜超势。

英文摘要:

In this work we compute relative periods for B-branes, realized in terms of divisors in a compact Calabi-Yau hypersurface, by means of direct integration. Although we exemplify the method of direct integration with a particular Calabi-Yau geometry, the recipe automatically generalizes for divisors in other Calabi-Yau geometries as well. From the calculated relative periods we extract double-logarithmic periods. These periods qualify to describe disk instanton generated N=1 superpotentials of the corresponding compact mirror Calabi-Yau geometry in the large volume regime. Finally we extract the integer invariants encoded in these brane superpotentials.
