Infinitesimal Carleson property for weighted measures induced by analytic self-maps of the unit disk
Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Springer, 2013-08)We prove that, for every α>−1, the pull-back measure φ(Aα) of the measure dAα(z)=(α+1)(1−|z|2)αdA(z), where A is the ...

Integration Operators in Average Radial Integrability Spaces of Analytic Functions
Aguilar-Hernández, Tanausú; Contreras Márquez, Manuel Domingo; Rodríguez Piazza, Luis (Springer, 2021)In this paper we characterize the boundedness, compactness, and weak compactness of the integration operators Tg(f)(z) ...

Invariant means and thin sets in harmonic analysis with applications to prime numbers
Lefèvre, Pascal; Rodríguez Piazza, Luis (Wiley, 2009-08)We first prove a localization principle characterising Lust-Piquard sets. We obtain that the union of two Lust-Piquard ...

Lp-valued measures without finite X-semivariation for 2 < p < ∞
Jefferies, Brian; Okada, Susumu; Rodríguez Piazza, Luis (Taylor & Francis, 2007)We show that for 1 ≤ p < ∞, the property that every Lp-valued vector measure has finite X-semivariation in Lp(μ, X) is ...

Nevanlinna counting function and Carleson function of analytic maps
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Springer, 2011-10)We show that the maximal Nevanlinna counting function and the Carleson function of analytic self-maps of the unit disk are equivalent, up to constants.

On approximation numbers of composition operators
Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Elsevier, 2012-04)We show that the approximation numbers of a compact composition operator on the weighted Bergman spaces Bα of the unit ...

On some random thin sets of integers
Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (American Mathematical Society, 2008-01)We show how different random thin sets of integers may have different behaviour. First, using a recent deviation inequality ...

On the Muskat problem: global in time results in 2D and 3D
Constantin, Peter; Córdoba Gazolaz, Diego; Gancedo García, Francisco; Rodríguez Piazza, Luis; Strain, Robert M. (Johns Hopkins University Press, 2016-12)This paper considers the three dimensional Muskat problem in the stable regime. We obtain a conservation law which provides ...

Some examples of compact composition operators on H2
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Elsevier, 2008-12-01)We construct, in an essentially explicit way, various composition operators on H2 and study their compactness or their ...

Some new properties of composition operators associated with lens maps
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Springer, 2013-05)We give examples of results on composition operators connected with lens maps. The first two concern the approximation ...

Some new thin sets of integers in harmonic analysis
Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Springer, 2002-12)We randomly construct various subsets A of the integers which have both smallness and largeness properties. They are small ...

Some revisited results about composition operators on Hardy spaces
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (European Mathematical Society, 2012)We generalize, on one hand, some results known for composition operators on Hardy spaces to the case of Hardy-Orlicz spaces ...

Some translation-invariant Banach function spaces which contain C0
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Polish Academy of Sciences, Institute of Mathematics, 2004)We produce several situations where some natural subspaces of classical Banach spaces of functions over a compact abelian group contain the space c0.
