Our first result is a noncommutative form of the Jessen-Marcinkiewicz-Zygmund theorem for the maximal limit of multiparametric martingales or ergodic means. It implies bilateral almost uniform convergence (a noncommutative analogue of almost everywhe

Let $\text{H}$ be a subgroup of some locally compact group $\text{G}$. Assume that $\text{H}$ is approximable by discrete subgroups and that $\text{G}$ admits neighborhood bases which are almost invariant under conjugation by finite subsets of $\text

In this paper we solve three problems in noncommutative harmonic analysis which are related to endpoint inequalities for singular integrals. In first place, we prove that an L-form of Hörmander's kernel condition suffices for the weak type (1,1) of

We establish precise regularity conditions for Lp-boundedness of Fourier multipliers in the group algebra of SLn.R/. Our main result is inspired by the Hörmander¿ Mikhlin criterion from classical harmonic analysis, although it is substantially and

Calder´on-Zygmund theory has been traditionally developed on metric measure spaces satisfying additional regularity properties. In the lack of good metrics, we introduce a new approach for general measure spaces which admit a Markov semigroup satisf

Given a measure μ of polynomial growth, we refine a deep result by David and Mattila to construct an atomic martingale filtration of supp (μ) which provides the right framework for a dyadic form of nondoubling harmonic analysis. Despite this filtra

We prove several results about the best constants in the Hausdorff-Young inequality for noncommutative groups. In particular, we establish a sharp local central version for compact Lie groups, and extend known results for the Heisenberg group. In add
