Lebesgue points of measures and non tangential convergence of Poisson-Hermite integrals
Guillermo Flores, Gustavo Garrigós, Beatriz Viviani
We study differentiability conditions on a complex measure at a point , in relation with the boundary convergence at that point of the Poisson-type integral…
Local cone multipliers and Cauchy-Szego projections in bounded symmetric domains
Fernando Ballesta Yagüe, Gustavo Garrigós
We show that the cone multiplier satisfies local - bounds only in the trivial range . To do so, we suitably adapt to this setting the proof…
Basis properties of the Haar system in limiting Besov spaces
Gustavo Garrigós, Andreas Seeger, Tino Ullrich
We study Schauder basis properties for the Haar system in Besov spaces . We give a complete description of the limiting cases, obtaining various positive r…
On uniform boundedness of dyadic averaging operators in spaces of Hardy-Sobolev type
Gustavo Garrigós, Andreas Seeger, Tino Ullrich
We give an alternative proof of recent results by the authors on uniform boundedness of dyadic averaging operators in (quasi-)Banach spaces of Hardy-Sobolev and Triebel-Lizorkin ty…
