伪卡拉比流

Pseudo-Calabi Flow

Xiuxiong Chen, Kai Zheng

摘要:

首先定义伪Calabi流为{方程 *} {{aligned}{{ \partial φ} \over { \partial t}}&= -f(φ),\triangle_v arphi f(φ)&= S(φ)- \ul S. {对齐}。\end{equation*}然后证明了该流的适定性,包括解的短时存在性、正则性和对初值的连续依赖性。其次,我们指出里奇曲率上的$L^\infty$界是伪Calabi流推广的障碍.最后,我们证明了如果在其Kähler类中存在一个cscK度量,那么对于它的一个小的$C^{2,α}$邻域中的任何初始势,伪Calabi流必须指数收敛到附近的一个cscK度量。

英文摘要:

We first define Pseudo-Calabi flow, as {equation*} {{aligned}{{\partial φ}\over {\partial t}}&= -f(φ), \triangle_varphi f(φ) &= S(φ) - \ul S.{aligned}. \end{equation*} Then we prove the well-posedness of this flow including the short time existence, the regularity of the solution and the continuous dependence on the initial data. Next, we point out that the $L^\infty$ bound on Ricci curvature is an obstruction to the extension of the pseudo-Calabi flow. Finally, we show that if there is a cscK metric in its Kähler class, then for any initial potential in a small $C^{2,α}$ neighborhood of it, the pseudo-Calabi flow must converge exponentially to a nearby cscK metric.
