$D_{k}$型ALF引力瞬子的粘合构造与非全纯极小球面的存在性

A gluing construction of $D_{k}$ ALF gravitational instantons and existence of non-holomorphic minimal spheres

Xuwen Zhu

AI总结:

本文拓展了Schroers--Singer中$D_{k}$型ALF引力瞬子的粘合构造至新情形,给出含非全纯极小球面的一般ALF空间类,结合Foscolo构造得到一大类含该球面的$K3$曲面。

摘要:

本笔记将Schroers--Singer中$D_{k}$型ALF引力瞬子的构造拓展到新情形:非线性叠加由$D_{1}$型Atiyah--Hitchin度量和$k-1$个$A_{0}$型Taub-NUT度量给出。随后给出一类一般ALF空间,其中每个空间都包含非全纯极小球面。结合Foscolo的构造,这得到一大类包含非全纯极小球面的$K3$曲面。

英文摘要:

This note extends the construction of $D_{k}$ ALF gravitational instantons in Schroers--Singer to a new case where the nonlinear superposition is given by the $D_{1}$ Atiyah--Hitchin metric and $k-1$ copies of $A_{0}$ Taub-NUT metrics. We then give a general class of ALF spaces such that each of them contains a non-holomorphic minimal sphere. Together with Foscolo's construction this gives a large class of $K3$ surfaces containing non-holomorphic minimal spheres.
