The Hardy spaces $H_{F I O}^{p} (R^{n})$ for Fourier integral operators for $p < 1$

Naijia Liu, Jan Rozendaal, Liang Song

We introduce the Hardy spaces $H_{F I O}^{p} (R^{n})$ for Fourier integral operators for $0 < p < 1$ , thereby extending earlier constructions for $1 \leq p \leq \infty$ .…

$H^{1}$ and $bmo$ regularity for wave equations with rough coefficients

Naijia Liu, Jan Rozendaal, Liang Song

We consider second-order hyperbolic equations with rough time-independent coefficients. Our main result is that such equations are well posed on the Hardy spaces $\mathcal{H}^{s,1}…
