Local Hardy spaces and summability of Fourier transforms

New Wiener amalgam spaces are introduced for local Hardy spaces. A general summability method, the so-called θ-summability is considered for multi-dimensional Fourier transforms. Under some conditions on θ, it is proved that the maximal operator of the θ-means is bounded from the amalgam space to W(Lp,ℓ∞). This implies the almost everywhere convergence of the θ-means for all f∈W(L1,ℓ∞)⊃L1.
