Low-temperature behavior of density-functional theory for metals based on density-functional perturbation theory and Sommerfeld expansion
Xavier Gonze, Christian Tantardini, Antoine Levitt
The temperature dependence of most solid-state properties is dominated by lattice vibrations, but metals display notable purely electronic effects at low temperature, such as the l…
Ratio limit theorem for renewal processes
Mikael Escobar-Bach, Alexandre Popier, Malo Sahin
We consider a renewal process which models a cumulative shock model that fails when the accumulation of shocks up-crosses a certain threshold. The ratio limit properties of the pro…
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…
Stochastic PDEs driven by G-Brownian motion and the associated Backward Doubly Stochastic Differential Equations
Laurent Denis, Jing Zhang
Our aim is to study the well-posedness of quasilinear stochastic partial differential equations driven by G-Brownian motion (GSPDEs for short) and the associated backward doubly st…
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…
