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

On some random thin sets of integers
(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 examples of compact composition operators on H2
(Elsevier, 2008-12-01)We construct, in an essentially explicit way, various composition operators on H2 and study their compactness or their ...

Hasse-Schmidt derivations, divided powers and differential smoothness
(Association des Annales de l'Institut Fourier, 2009)Let k be a commutative ring, A a commutative k-algebra and D the filtered ring of k-linear differential operators of A. ...

The canonical injection of the Hardy-Orlicz space HΨ into the Bergman–Orlicz space BΨ
(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..

On minimax-regret Huff location models
(Elsevier, 2011-01)We address the following single-facility location problem: a firm is entering into a market by locating one facility in a ...

Nevanlinna counting function and Carleson function of analytic maps
(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.

Some revisited results about composition operators on Hardy spaces
(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 ...

On the modules of m-integrable derivations in non-zero characteristic
(Elsevier, 2012-03-20)Let k be a commutative ring and A a commutative k-algebra. Given a positive integer m, or m = ∞, we say that a k-linear ...
