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

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 present a general approach to sparse domination based on single-scale $$L^p$$ -improving as a key assumption. The results are formulated in the setting of metric spaces of homogeneous type and avoid completely the use of dyadic-probabilistic techn

The usual one third trick allows to reduce problems involving general cubes to a countable family. Moreover, this covering lemma uses only dyadic cubes, which allows to use nice martingale properties in harmonic analysis problems. We consider alterna

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 obtain a complete characterization of the weak-type ( 1 , 1 ) (1,1) for Haar shift operators in terms of generalized Haar systems adapted to a Borel measure μ \mu in the operator-valued setting. The main technical tool in our method is a noncommu

It is shown that if a Markov map T on a noncommutative probability space M has a spectral gap on L(M), then it also has one on L(M) for 1 < p < ∞. For fixed p, the converse also holds if T is factorizable. Some results are also new for classical pr
