本文证明了含零维非klt中心且具有非零约化边界的正常稳定曲面偶的最小体积为1/42,并唯一确定了达到该值的曲面偶,同时指出1/42是体积集的无限积累点。
AI 中文摘要
我们证明了,在具有非零约化边界且包含零维非klt中心的正常稳定曲面偶中,最小体积为$\ rac{1}{42}$,并证明了达到此最小值的曲面偶在同构意义下是唯一的。作为应用,我们证明了$\ rac{1}{42}$是正常稳定曲面体积集的无限积累点。
英文摘要
We show that the minimum volume among normal stable surface pairs with nonzero reduced boundary containing a zero-dimensional non-klt center is $\frac{1}{42}$, and show that the surface pair attaining this minimum is unique up to isomorphism. As an application, we show that $\frac{1}{42}$ is an infinite accumulation point of the volume set of normal stable surfaces.
