Energy estimates for level sets of holomorphic functions and universal counterexamples to Calderón-Zygmund theory
Yifei Pan, Guokuan Shao, Jianfei Wang +1
We demonstrate that the failure of regularity in Calderón-Zygmund theory is a universal phenomenon: every non-constant holomorphic function in $\C^n$ generates a counterexam…

On the Local Regularity of the Hilbert Transform
Yifei Pan, Jianfei Wang, Yu Yan
In this paper the local regularity of the Hilbert transform is considered, and local smoothness and real analyticity results are obtained.
