ABSTRACT

We introduce a new function space, denoted by HFIO1(ℝn), which is preserved by the algebra of Fourier integral operators of order 0 associated to canonical transformations. A subspace of L1 (ℝn), this space in many aspects resembles the real Hardy space of Fefferman-Stein. In particular, we obtain an atomic characterization of HFIO1 (ℝn). In contrast to the standard Hardy space, these atoms are localized in frequency space as well as in real space.
