Abstract
We study a family of Fourier integral operators by allowing their symbols to
satisfy a multi-parameter differential inequality on R^N. We show that these
operators of order -(N-1)/2 are bounded from classical, atom decomposable
H^1-Hardy space to L^1(R^N). Consequently, we obtain a sharp L^p-regularity
result due to Seeger, Sogge and Stein.
