Almost everywhere convergence of Bochner--Riesz means for the twisted Laplacian

Eunhee Jeong, Sanghyuk Lee, Jaehyeon Ryu

Let $\mathcal{L}$ denote the twisted Laplacian in ${\mathbb{C}}^d$. We study almost everywhere convergence of the Bochner--Riesz mean $S_t^{\delta }(\mathcal{L})f$ of $f\in L^p({\mathbb{C}}^d)$…
