有理曲面奇点和自反模的变形及其在触发器中的应用

Deformations of rational surface singularities and reflexive modules with an application to flops

Trond Stølen Gustavsen, Runar Ile

摘要:

在一个自反模中爆破一个有理曲面奇点给出了一个(任何)由最小分解支配的部分分解。主要定理表明如何变形的对(奇异性,模块)涉及到变形的相应对的部分决议和局部自由严格变换,并变形的基础空间。这些结果暗示了最近对小分辨率和失败的一些认识。

英文摘要:

Blowing up a rational surface singularity in a reflexive module gives a (any) partial resolution dominated by the minimal resolution. The main theorem shows how deformations of the pair (singularity, module) relates to deformations of the corresponding pair of partial resolution and locally free strict transform, and to deformations of the underlying spaces. The results imply some recent conjectures on small resolutions and flops.
