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

Guangqing Wang, Suixin He, Lihua Zhang

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