The largest eigenvalues of sample covariance matrices for a spiked population: diagonal case
Delphine Féral, Sandrine Péché
We consider large complex random sample covariance matrices obtained from "spiked populations", that is when the true covariance matrix is diagonal with all but finitely many eigen…
Minoration de la hauteur de Neron-Tate sur les surfaces abeliennes
Fabien Pazuki
This paper contains results concerning a conjecture made by Lang and Silverman predicting a lower bound for the canonical height on abelian varieties of dimension 2 over number fie…
The second moment of Dirichlet twists of Hecke -functions
Peng Gao, Rizwanur Khan, Guillaume Ricotta
Fix a Hecke cusp form , and consider the -function of twisted by a primitive Dirichlet character. As we range over all primitive characters of a large modulus , what i…
High order resolution of the Maxwell-Fokker-Planck-Landau model intended for ICF applications
Roland Duclous, Bruno Dubroca, Francis Filbet +1
A high order, deterministic direct numerical method is proposed for the nonrelativistic Vlasov-Maxwell system, coupled with Fokker-Planck-Landau type…
Discovery of gamma-ray emission from the shell-type supernova remnant RCW 86 with H.E.S.S
HESS Collaboration, F. Aharonian
The shell-type supernova remnant (SNR) RCW 86, possibly associated with the historical supernova SN 185, with its relatively large size (about 40' in diameter) and the presence of…
(2+2)-free posets, ascent sequences and pattern avoiding permutations
Mireille Bousquet-Mélou, Anders Claesson, Mark Dukes +1
We present bijections between four classes of combinatorial objects. Two of them, the class of unlabeled (2+2)-free posets and a certain class of involutions (or chord diagrams), a…
Algebraic continued fractions in F_q((T^{-1})) and recurrent sequences in F_q
Alain Lasjaunias
There exists a particular subset of algebraic power series over a finite field which, for different reasons, can be compared to the subset of quadratic real numbers. The continued…
Existence and stability of noncharacteristic boundary-layers for the compressible Navier-Stokes and viscous MHD equations
Olivier Gues, Guy Metivier, Mark Williams +1
For a general class of hyperbolic-parabolic systems including the compressible Navier-Stokes and compressible MHD equations, we prove existence and stability of noncharacteristic v…
Coherent forward stimulated Brillouin scattering of a spatially incoherent laser beam in a plasma and its effect on beam spray
M. Grech, G. Riazuelo, D. Pesme +2
A statistical model for forward stimulated Brillouin scattering (FSBS) is developed for a spatially incoherent, monochromatic, laser beam propagating in a plasma. A threshold for t…
Inégalités de Poincaré cinétiques
Pascal Azerad, Stéphane Brull
In this note we prove Poincaré type inequalities for a family of kinetic equations. We apply this inequality to the variational solution of a linear kinetic model.
Families of prudent self-avoiding walks
Mireille Bousquet-Mélou
A self-avoiding walk (SAW) on the square lattice is prudent if it never takes a step towards a vertex it has already visited. Prudent walks differ from most classes of SAW that hav…
Discovery of a VHE gamma-ray source coincident with the supernova remnant CTB 37A
HESS Collaboration, F Aharonian
The supernova remnant (SNR) complex CTB 37 is an interesting candidate for observations with Very High Energy (VHE) gamma-ray telescopes such as H.E.S.S. In this region, three SNRs…
Chandra and H.E.S.S. observations of the Supernova Remnant CTB 37B
HESS Collaboration, F. Aharonian
The >100 GeV gamma-ray source, HESS J1713-381, apparently associated with the shell-type supernova remnant (SNR) CTB 37B, was discovered using H.E.S.S. in 2006. X-ray follow-up obs…
Lower bounds for measurable chromatic numbers
Christine Bachoc, Gabriele Nebe, Fernando Mario de Oliveira Filho +1
The Lovasz theta function provides a lower bound for the chromatic number of finite graphs based on the solution of a semidefinite program. In this paper we generalize it so that i…
