广义Taub-NUT空间上的Dirac算子

The Dirac operator on generalized Taub-NUT spaces

Andrei Moroianu, Sergiu Moroianu

摘要:

我们找到了在紧致Kähler基上构造成锥丛的自旋流形上不存在调和$L^2$旋量的充分条件。这些条件满足某些扰动的欧几里德度量,也为广义陶布NUT度量的Iwai-Katayama,从而证明了一个猜想的Vi \csinescu和第二作者。

英文摘要:

We find sufficient conditions for the absence of harmonic $L^2$ spinors on spin manifolds constructed as cone bundles over a compact Kähler base. These conditions are fulfilled for certain perturbations of the Euclidean metric, and also for the generalized Taub-NUT metrics of Iwai-Katayama, thus proving a conjecture of Vi\csinescu and the second author.
