中文摘要 AI 辅助
我们引入了有向凸Calabi-Yau三维奇点的通用被单(universal quilt)概念,并构造了通用被单本身为光滑Calabi-Yau三维流形的例子。这类被单旨在包含给定奇点的所有平展分解(crepant resolutions)。为得到通用被单,我们实现了一种算法,可计算任意给定平面多边形的所有三角剖分。我们还引入了被单栈(quilt stack)的概念,以解决寻找给定奇点之前最可能的光滑构型这一问题。
英文摘要
We introduce the notion of universal quilt for toric CY3 singularities and construct examples when the universal quilts are themselves smooth Calabi-Yau threefolds. Such quilts are designed to contain all of the crepant resolutions of the given singularity. To obtain universal quilts we implement an algorithm that computes all triangulations for any given planar polygon. We also introduce the notion of quilt stack, to address the question of finding the most likely smooth configuration preceding a given singularity.
