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{-Δ}}f(x) = \frac{1}{(2π)^d}\int_{\mathbb{R}^d} e^{i(x \cdot ξ\, + t|ξ…

Endpoint regularity of general Fourier integral operators

Xiangrong Zhu, Wenjuan Li

Let $n \geq 1, 0 < ρ < 1, max {ρ, 1 - ρ} \leq δ \leq 1$ and $m_{1} = ρ - n + (n - 1) min {\frac{1}{2}, ρ} + \frac{1 - δ}{2} .$ If the amplitude $a$ belongs to the Hörmander class $S_{ρ, δ}^{m_{1}}$ and $ϕ\in…
