Dolbeault复形的Witten变形

The Witten deformation of the Dolbeault complex

Jesús Álvarez López, Peter Gilkey

摘要:

我们引入了任意复Kähler流形的Dolbeault复形的Witten-Novikov型扰动$\bar\partial_{\barω}$,定义为$ω$型的形式$(1,0)$与$\partialω=0$ .我们给出了一个明确的描述相关的指数密度表明,它表现出一个非平凡的依赖于$ω$。低阶热不变量为零。

英文摘要:

We introduce a Witten-Novikov type perturbation $\bar\partial_{\barω}$ of the Dolbeault complex of any complex Kähler manifold, defined by a form $ω$ of type $(1,0)$ with $\partialω=0$. We give an explicit description of the associated index density which shows that it exhibits a nontrivial dependence on $ω$. The heat invariants of lower order are shown to be zero.
