Artin approximation compatible with a change of variables
Goulwen Fichou, Ronan Quarez, Masahiro Shiota
We propose a version of the classical Artin approximation which allows to perturb the variables of the approximated solution. Namely, it is possible to approximate a formal solutio…
Hiding in plain view: Colloidal self-assembly from polydisperse populations
Bernard Cabane, Joaquim Li, Franck Artzner +5
We report small-angle x-ray scattering (SAXS) experiments on aqueous dispersions of colloidal silica with a broad monomodal size distribution (polydispersity 18%, size 8 nm). Over…
Farrell-Jones via Dehn fillings
Yago Antolín, Rémi Coulon, Giovanni Gandini
Following the approach of Dahmani, Guirardel and Osin, we extend the group theoretical Dehn filling theorem to show that the pre-images of infinite order elements have a certain st…
Masses of the components of SB2 binaries observed with Gaia. II. Masses derived from PIONIER interferometric observations for Gaia validation
J. -L. Halbwachs, H. M. J. Boffin, J. -B. Le Bouquin +15
In anticipation of the Gaia astrometric mission, a sample of spectroscopic binaries is being observed since 2010 with the Sophie spectrograph at the Haute--Provence Observatory. Ou…
On numerical Landau damping for splitting methods applied to the Vlasov-HMF model
Erwan Faou, Romain Horsin, Frédéric Rousset
We consider time discretizations of the Vlasov-HMF (Hamiltonian Mean-Field) equation based on splitting methods between the linear and non-linear parts. We consider solutions start…
Distributions of traces of Frobenius for smooth plane curves over finite fields
Reynald Lercier, Christophe Ritzenthaler, Florent Rovetta +2
In a previous article, we obtained data on the distribution of traces of Frobenius of non-hyperelliptic genus curves over small finite fields. In the present one, we give a heu…
A search of the Orion spur for continuous gravitational waves using a "loosely coherent" algorithm on data from LIGO interferometers
J. Aasi, B. P. Abbott, R. Abbott +920
We report results of a wideband search for periodic gravitational waves from isolated neutron stars within the Orion spur towards both the inner and outer regions of our Galaxy. As…
The existence of Zariski dense orbits for polynomial endomorphisms of the affine plane
Junyi Xie
In this paper we prove the following theorem. Let be a dominate polynomial endomorphisms defined over an algebraically closed field of…
Generalized Stieltjes Transforms of Compactly-Supported Probability Distributions: Further Examples
Nizar Demni
For two families of beta distributions, we show that the generalized Stieltjes transforms of their elements may be written as elementary functions (powers and fractions) of the Sti…
A role for ATP-dependent chromatin remodeling in the hierarchical cooperativity between noninteracting transcription factors
Denis Michel
Chromatin remodeling machineries are abundant and diverse in eukaryotic cells. They have been involved in a variety of situations such as histone exchange and DNA repair, but their…
Stable integrated hyper-parametric oscillator based on coupled optical microcavities
Andrea Armaroli, Patrice Féron, Yannick Dumeige
We propose a flexible scheme based on three coupled optical microcavities which permits to achieve stable oscillations in the microwave range, the frequency of which depends only o…
Excitable-like chaotic pulses in the bounded-phase regime of an opto-radiofrequency oscillator
Marco Romanelli, Aurélien Thorette, Marc Brunel +2
We report theoretical and experimental evidence of chaotic pulses with excitable-like properties in an opto-radiofrequency oscillator based on a self-injected dual-frequency laser.…
A chiral rhenium complex with predicted high parity violation effects: synthesis, stereochemical characterization by VCD spectroscopy and quantum chemical calculations
Nidal Saleh, Samia Zrig, Thierry Roisnel +5
With their rich electronic, vibrational, rotational and hyperfine structure, molecular systems have the potential to play a decisive role in precision tests of fundamental physics.…

Let be an almost simple simply-connected affine algebraic group over an algebraically closed field of characteristic . If has type , or , we assu…
Asymptotic Preserving numerical schemes for multiscale parabolic problems
Nicolas Crouseilles, Mohammed Lemou, Gilles Vilmart
We consider a class of multiscale parabolic problems with diffusion coefficients oscillating in space at a possibly small scale . Numerical homogenization methods are…
The multilayer shallow water system in the limit of small density contrast
Vincent Duchêne
We study the inviscid multilayer Saint-Venant (or shallow-water) system in the limit of small density contrast. We show that, under reasonable hyperbolicity conditions on the flow…
Formal confluence of quantum differential operators
Bernard Le Stum, Adolfo Quirós
We prove that a usual differential operator is formally the limit of quantum differential operators. For this purpose, we introduce the notion of twisted differential operator of i…
Volume integral equations for electromagnetic scattering in two dimensions
Martin Costabel, Eric Darrigrand, Hamdi Sakly
We study the strongly singular volume integral equation that describes the scattering of time-harmonic electromagnetic waves by a penetrable obstacle. We consider the case of a cyl…

Bernard Helffer, Yuri Kordyukov, Nicolas Raymond +1
This paper deals with semiclassical asymptotics of the three-dimensional magnetic Laplacian in presence of magnetic confinement. Using generic assumptions on the geometry of the co…
Multiscale numerical schemes for kinetic equations in the anomalous diffusion limit
Nicolas Crouseilles, Hélène Hivert, Mohammed Lemou
We construct numerical schemes to solve kinetic equations with anomalous diffusion scaling. When the equilibrium is heavy-tailed or when the collision frequency degenerates for sma…
Co-periodic stability of periodic waves in some Hamiltonian PDEs
Sylvie Benzoni-Gavage, Colin Mietka, L. Miguel Rodrigues
The stability of periodic traveling wave solutions to dispersive PDEs with respect to `arbitrary' perturbations is still widely open. The focus is put here on stability with respec…
