Calder{ó}n splitting and weak solutions for Navier-Stokes equations with initial data in weighted L p spaces
Pierre Gilles Lemarié-Rieusset
We show the existence of global weak solutions of the 3D Navier-Stokes equations with initial velocity in the weighted spaces , using Calder{ó}n splitting L p L 2…
A model-free Screening procedure
J Dedecker, M L Taupin, A S Tocquet
In this article, we propose a generic screening method for selecting explanatory variables correlated with the response variable Y . We make no assumptions about the existence of a…
Weak Error on the densities for the Euler scheme of stable additive SDEs with Besov drift
Mathis Fitoussi, Elena Issoglio, Stéphane Menozzi
We are interested in the Euler-Maruyama dicretization of the formal SDE, , where is a symmetric isotropic d dimensional stable process of index $α\in (1,2…
Global mild solutions in a critical setting for a forced fractional Boussinesq system
Diego Chamorro, Maxence Mansais
We study here mild solutions for the forced, incompressible fractional Boussinesq system. Under suitable estimates for the terms involved (in an adapted functional framework) we ca…
New weighted Riesz-type pointwise inequalities and applications to generalized Sobolev estimates
Diego Chamorro, Anca-Nicoleta Marcoci, Liviu-Gabriel Marcoci
In this article we study some new pointwise inequalities between rough singular integral operators, weighted maximal functions of the gradient and weighted Morrey spaces. These poi…
Total progeny for spectrally negative branching L{é}vy processes with absorption
Christophe Profeta
We consider a spectrally negative branching L{é}vy process in which particles are killed upon crossing below zero. It is known that such a process becomes extinct almost surely if…
