Calabi-Yau流形极值变换和极值触发的连续性

Continuity of Extremal Transitions and Flops for Calabi-Yau Manifolds

Xiaochun Rong, Yuguang Zhang

摘要:

本文研究了Calabi-Yau流形上Ricci平坦Kähler度量在代数几何运算下的行为:极值变换或翻转。我们证明了Candelas和de la Ossa猜想的一个版本:与极值变换和翻转相关的Ricci平坦Calabi-Yau流形可以通过由连续的Ricci平坦Calabi-Yau流形族和Gromov-Hausdorff拓扑中的紧度量空间组成的路径连接。在证明主要结果的一个重要步骤中,建立了Calabi-Yau流形上Ricci平坦Kähler度量沿光滑的收敛性,这是一个独立的结果.

英文摘要:

In this paper, we study the behavior of Ricci-flat Kähler metrics on Calabi-Yau manifolds under algebraic geometric surgeries: extremal transitions or flops. We prove a version of Candelas and de la Ossa's conjecture: Ricci-flat Calabi-Yau manifolds related by extremal transitions and flops can be connected by a path consisting of continuous families of Ricci-flat Calabi-Yau manifolds and a compact metric space in the Gromov-Hausdorff topology. In an essential step of the proof of our main result, the convergence of Ricci-flat Kähler metrics on Calabi-Yau manifolds along a smoothing is established, which can be of independent interests.
