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 $L^1$ regularity in Calderón-Zygmund theory is a universal phenomenon: every non-constant holomorphic function in $\C^n$ generates a counterexam…
