Notes on Regularity of Fourier integral operators with symbol in $S_{0,\hat{I}´}^m$

Guangqing Wang, Suixin He

Let $T_{a,\ddot{I}†}$ be a Fourier integral operator defined with $a\in S_{0,\hat{I}´}^m(0\le \hat{I}´<1)$ and $\ddot{I}†\in \hat{I}{¦}^2$ satisfying the strong non-degenerate condition. We demonstrate that whe…
