Endpoint estimates for maximal operators associated to the wave equation

Chu-Hee Cho, Sanghyuk Lee, Wenjuan Li

We consider the $H^{s}$ -- $L^{q}$ maximal estimates associated to the wave operator \begin{equation*} e^{ it\sqrt{-Î}}f(x) = \frac{1}{(2Ï)^d}\int_{\mathbb{R}^d} e^{i(x \cdot Î¾\, +…

Endpoint regularity of general Fourier integral operators

Xiangrong Zhu, Wenjuan Li

Let $n \geq 1, 0 < I ¨ < 1, max {I ¨ , 1 - I ¨ } \leq I^´ \leq 1$ and $m_{1} = I ¨ - n + (n - 1) min {\frac{1}{2}, I ¨ } + \frac{1 - I ^ ´}{2} .$ If the amplitude $a$ belongs to the HÃ¶rmander class $S_{I ¨ , I^´}^{m_{1}}$ …
