Weighted weak-type (1, 1) inequalities for pseudo-differential operators with symbol in $S_{0,\hat{I}´}^m$

Guangqing Wang, Suixin He, Lihua Zhang

Let $T_a$ be a pseudo-differential operator defined by exotic symbol $a$ in Hörmander class $S_{0,\hat{I}´}^m$ with $m\in \mathbb{R}$ and $0\le \hat{I}´\le 1$. It is well-known that the…
