Well-posedness for Hall-magnetohydrodynamics
Dongho Chae, Pierre Degond, Jian-Guo Liu
We prove local existence of smooth solutions for large data and global smooth solutions for small data to the incompressible, resitive, viscous or inviscid Hall-MHD model. We also…
On Ornstein-Uhlenbeck driven by Ornstein-Uhlenbeck processes
Bernard Bercu, Frederic Proia, Nicolas Savy
We investigate the asymptotic behavior of the maximum likelihood estimators of the unknown parameters of positive recurrent Ornstein-Uhlenbeck processes driven by Ornstein-Uhlenbec…
Viscosity solutions to complex Hessian equations
Lu Hoang Chinh
We study viscosity solutions to complex hessian equations. In the local case, we consider a bounded domain in the standard Kähler form in an…
Two Newton methods on the manifold of fixed-rank matrices endowed with Riemannian quotient geometries
P. -A. Absil, Luca Amodei, Gilles Meyer
We consider two Riemannian geometries for the manifold of all matrices of rank . The geometries are induced on …
Means in complete manifolds: uniqueness and approximation
Marc Arnaudon, Laurent Miclo
Let be a complete Riemannian manifold, $N\in \NN$ and . We prove that almost everywhere on for Lebesgue measure in , the measure $\di μ(x)…
A thin film approximation of the Muskat problem with gravity and capillary forces
Philippe Laurencot, Bogdan-Vasile Matioc
Existence of nonnegative weak solutions is shown for a thin film approximation of the Muskat problem with gravity and capillary forces taken into account. The model describes the s…
Some open questions on anti-de Sitter geometry
Thierry Barbot, Francesco Bonsante, Jeffrey Danciger +6
We present a list of open questions on various aspects of AdS geometry, that is, the geometry of Lorentz spaces of constant curvature -1. When possible we point out relations with…
Highly anisotropic temperature balance equation and its asymptotic-preserving resolution
Alexei Lozinski, Jacek Narski, Claudia Negulescu
This paper deals with the numerical study of a nonlinear, strongly anisotropic heat equation. The use of standard schemes in this situation leads to poor results, due to the high a…
Traffic Instabilities in Self-Organized Pedestrian Crowds
Mehdi Moussaid, Elsa G. Guillot, Mathieu Moreau +7
In human crowds as well as in many animal societies, local interactions among individuals often give rise to self-organized collective organizations that offer functional benefits…
The parabolic-parabolic Keller-Segel system with critical diffusion as a gradient flow in $\RR^d$,
Adrien Blanchet, Philippe Laurençot
It is known that, for the parabolic-elliptic Keller-Segel system with critical porous-medium diffusion in dimension $\RR^d$, (also referred to as the quasilinear Smolucho…
Eigenvalue variance bounds for Wigner and covariance random matrices
Sandrine Dallaporta
This work is concerned with finite range bounds on the variance of individual eigenvalues of Wigner random matrices, in the bulk and at the edge of the spectrum, as well as for som…
