Abstract
In this paper, we survey some multiplier theorems and their applications to estimates for wave equation in Hardy spaces $H^p(\Bbb R^n)$. We also prove $H^p$ boundedness for Calder\'on-Zygmund operators of type $\sigma$ which can be considered as a generalization of classical singular integral operators. Using these results, we discuss some recent progress in $H^p$ regularity properties of the solving operators for hyperbolic equations.
