Poisson type generators for L^1(R)

Gerard Ascensi, Joaquim Bruna

We characterize the discrete sets L of the real line such that {f(t-l), l in L} span L^1(R), f being an L^1(R)-function whose Fourier transform behaves like the one of the Poisson…

L^p estimates for Riesz transforms on forms in the Poincare space H^n

Joaquim Bruna

Using hyperbolic form convolution with doubly isometry-invariant kernels, the explicit expression of the inverse of the de Rham laplacian acting on m-forms in the Poincaré space is…

Completeness in $L^{1} (R)$ of discrete translates

Joaquim Bruna, Alexander Olevskii, Alexander Ulanovskii

We characterize, in terms of the Beurling-Malliavin density, the discrete spectra $Λ \subset R$ for which a generator exists, that is a function $ϕ \in L^{1} (R)$ such that its $Λ$ -tra…
