Donaldson-Futaki不变量的局部化

Localizing the Donaldson-Futaki invariant

Eveline Legendre

摘要:

利用等变定域公式证明了当中心纤维是光滑的或具有轨道奇点时,紧致光滑(K{ä}hler)测试位形的Donaldson-Futaki不变量与诱导作用在中心纤维上的Futaki不变量是一致的.我们还将变形的Donaldson-Futaki不变量局部化到法锥上。

英文摘要:

We use the equivariant localization formula to prove that the Donaldson-Futaki invariant of a compact smooth (K{ä}hler) test configuration coincides with the Futaki invariant of the induced action on the central fiber when this fiber is smooth or have orbifold singularities. We also localize the Donaldson-Futaki invariant of the deformation to the normal cone.
