摘要:

最近关于弦论之间的对偶性和它们的模空间的连通性的结果,似乎对建立基础理论的唯一性大有帮助。对于可以作为超曲面嵌入复曲面簇中的大类Calabi-Yau 3-folds,通过奇异极限的数学连通性的证明通过使用关于某些单权或多权系统的最大多面体而大大简化。我们确定在这种方法中发生的多个权重系统。我们表明,所有相应的卡-丘流形之间的连接和CICY的网络。这几乎完成了环面卡-丘超曲面连通性的证明。

英文摘要:

Recent results on duality between string theories and connectedness of their moduli spaces seem to go a long way toward establishing the uniqueness of an underlying theory. For the large class of Calabi-Yau 3-folds that can be embedded as hypersurfaces in toric varieties the proof of mathematical connectedness via singular limits is greatly simplified by using polytopes that are maximal with respect to certain single or multiple weight systems. We identify the multiple weight systems occurring in this approach. We show that all of the corresponding Calabi-Yau manifolds are connected among themselves and to the web of CICY's. This almost completes the proof of connectedness for toric Calabi-Yau hypersurfaces.
