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.

Strongly compact algebras
Lacruz Martín, Miguel Benito; Lomonosov, Victor; Rodríguez Piazza, Luis (Real Academia de Ciencias Exactas, Fisicas y Naturales, 2006)An algebra of bounded linear operators on a Hilbert space is said to be strongly compact if its unit ball is relatively ...

The canonical injection of the Hardy-Orlicz space HΨ into the Bergman–Orlicz space BΨ
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Polish Academy of Sciences, Institute of Mathematics, 2011)We study the canonical injection from the Hardy-Orlicz space HΨ into the Bergman–Orlicz space BΨ..

Thin sets of integers in Harmonic analysis and p-stable random Fourier series
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Springer, 2011-06)We investigate the behavior of some thin sets of integers defined through random trigonometric polynomial when one replaces ...

Two results on composition operators on the Dirichlet space
Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Elsevier, 2015-06-15)We show that the decay of approximation numbers of compact composition operators on the Dirichlet space D can be as slow ...

Weak compactness and Orlicz spaces
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Polish Academy of Sciences (Institute of Mathematics), 2008)We give new proofs that some Banach spaces have Peczynski's property (V)
