Average radial integrability spaces of analytic functions
Aguilar-Hernández, Tanausú; Contreras Márquez, Manuel Domingo; Rodríguez Piazza, Luis (Academic Press Inc., 2022)In this paper we introduce the family of spaces RM(p, q), 1 ≤ p, q ≤ +∞. They are spaces of holomorphic functions in the ...

Compact composition operators on the Dirichlet space and capacity of sets of contact points
Lefèvre, Pascal; Li, Daniel; Queffélec, Hervé; Rodríguez Piazza, Luis (Elsevier, 2013-02-15)We prove several results about composition operators on the Dirichlet space D⁎. For every compact set K⊆∂D of logarithmic ...

Extended eigenvalues of composition operators
Lacruz Martín, Miguel Benito; León Saavedra, Fernando; Petrovic, Srdjan; Rodríguez Piazza, Luis (Elsevier, 2021-12-15)A complex scalar λ is said to be an extended eigenvalue of a bounded linear operator A on a complex Hilbert space if there ...

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 ...

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 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 ...

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 ...
