尖点奇点的等变光滑化

Equivariant smoothing of cusp singularities

Yunfeng Jiang

AI总结:

本研究将Looijenga的曲面尖点奇点光滑化猜想推广到等变情形,证明了容许单参数光滑化的尖点奇点的光滑化可由局部完全交尖点的光滑化诱导,为半对数典范曲面上lci覆叠模叠的存在性提供了证据。

摘要:

我们将关于曲面尖点奇点光滑化的Looijenga猜想推广到等变情形。此外,我们证明:对任意容许单参数光滑化的尖点奇点,其光滑化总能由局部完全交尖点的光滑化诱导。该结果为半对数典范曲面上的lci覆叠的模叠的存在性提供了证据。

英文摘要:

We generalize Looijenga's conjecture for smoothing surface cusp singularities to the equivariant setting. Moreover, we prove that for any cusp singularity which admits a one-parameter smoothing, the smoothing can always be induced by smoothing of locally complete intersection cusps. The result provides evidence for the existence of the moduli stack of $\lci$ covers over semi-log-canonical surfaces.
