-ball superradiance: Analytical approach
Guo-Dong Zhang, Shuang-Yong Zhou, Meng-Fan Zhu
It was recently discovered that waves scattering off a -ball can extract energy from it. We present an analytical treatment of this process by adopting a multi-step function app…

Laplace comparison on Kähler Ricci flow and convergence
Gang Tian, Qi S. Zhang, Zhenlei Zhang +2
We first prove a uniform integral Laplace comparison result for the Kähler Ricci flow on Fano manifolds which depends only on the initial metric. As an application, using Cheeger-…
