Approximation numbers of composition operators on the Dirichlet space
Pascal Lefèvre, Daniel Li, Luis Rodriguez-Piazza +1
We study the decay of approximation numbers of compact composition operators on the Dirichlet space. We give upper and lower bounds for these numbers. In particular, we improve on…
Autour de pratiques algébriques de Poincaré : héritages de la réduction de Jordan
Frederic Brechenmacher
The legacy of Jordan's canonical form on Poincaré's algebraic practices. This paper proposes a transversal overview on Henri Poincaré's early works (1878-1885). Our investigations…
La fonte algébrique des Méthodes nouvelles de la mécanique céleste d'Henri Poincaré
Frederic Brechenmacher
Poincaré's approach to the three body problem has often been celebrated as a starting point of chaos theory in relation to the investigation of dynamical systems. Yet, Poincaré's s…
Ergodicity breaking in geometric Brownian motion
Ole Peters, William Klein
Geometric Brownian motion (GBM) is a model for systems as varied as financial instruments and populations. The statistical properties of GBM are complicated by non-ergodicity, whic…
Ring Endomorphisms with Large Images
André Leroy, Jerzy Matczuk
The notion of ring endomorphisms having large images is introduced. Among others, injectivity and surjectivity of such endomorphisms are studied. It is proved, in particular, that…
ADS modules
Adel Alahmadi, S. K. Jain, André Leroy
We study the class of ADS rings and modules introduced by Fuchs. We give some connections between this notion and classical notions such as injectivity and quasi-continuity. A simp…
