Hopf algebras: motivations and examples
G. H. E. Duchamp, P. Blasiak, A. Horzela +2
This paper provides motivation as well as a method of construction for Hopf algebras, starting from an associative algebra. The dualization technique involved relies heavily on the…
Existence and stability of viscous shock profiles for 2-D isentropic MHD with infinite electrical resistivity
Blake Barker, Olivier Lafitte, Kevin Zumbrun
For the two-dimensional Navier--Stokes equations of isentropic magnetohydrodynamics (MHD) with -law gas equation of state, , and infinite electrical resistivity, we carr…
Determination of the Boltzmann constant by laser spectroscopy as a basis for future measurements of the thermodynamic temperature
Cyril Lemarchand, Khelifa Djerroud, Benoît Darquié +6
In this paper, we present the latest results on the measurement of the Boltzmann constant kB, by laser spectroscopy of ammonia at 10 ?m. The Doppler absorption profile of a ro-vibr…
Strong approximations in a charged-polymer model
Yueyun Hu, Davar Khoshnevisan
We study the large-time behavior of the charged-polymer Hamiltonian of Kantor and Kardar [Bernoulli case] and Derrida, Griffiths, and Higgs [Gaussian case], using strong appr…
Ionic high-pressure form of elemental boron
Artem R. Oganov, Jiuhua Chen, Carlo Gatti +7
Boron is an element of fascinating chemical complexity. Controversies have shrouded this element since its discovery was announced in 1808: the new 'element' turned out to be a com…
Boron: a Hunt for Superhard Polymorphs
A. R. Oganov, V. L. Solozhenko
Boron is a unique element, being the only element, all known polymorphs of which are superhard, and all of its crystal structures are distinct from any other element. The electron-…
Measurement of the Boltzmann constant by the Doppler broadening technique at a 3,8x10-5 accuracy level
Khelifa Djerroud, Cyril Lemarchand, Alexandre Gauguet +7
In this paper, we describe an experiment performed at the Laboratoire de Physique des Lasers and dedicated to an optical measurement of the Boltzmann constant. With the proposed in…
An agile laser with ultra-low frequency noise and high sweep linearity
Haifeng Jiang, Fabien Kefelian, Pierre Lemonde +2
We report on a fiber-stabilized agile laser with ultra-low frequency noise. The frequency noise power spectral density is comparable to that of an ultra-stable cavity stabilized la…
Ergodic solenoidal homology: Realization theorem
Vicente Muñoz, Ricardo Perez-Marco
We define generalized currents associated with immersions of abstract oriented solenoids with a transversal measure. We realize geometrically the full real homology of a compact ma…
Circular tests for HSM machine tools: Bore machining application
Laurent Tapie, Kwamiwi Mawussi, Bernard Anselmetti
Today's High-Speed Machining (HSM) machine tool combines productivity and part quality. The difficulty inherent in HSM operations lies in understanding the impact of machine tool b…
Ergodic solenoids and generalized currents
Vicente Muñoz, Ricardo Perez-Marco
We introduce the concept of solenoid as an abstract laminated space. We do a thorough study of solenoids, leading to the notion of ergodic and uniquely ergodic solenoids. We define…
Derived functors of non-additive functors and homotopy theory
Lawrence Breen, Roman Mikhailov
We develop a functorial approach to the study of the homotopy groups of spheres and Moore spaces , based on the Curtis spectral sequence and the decomposition of Lie functo…
Statistics on Graphs, Exponential Formula and Combinatorial Physics
L. Poinsot, G. H. E. Duchamp, S. Goodenough +1
The concern of this paper is a famous combinatorial formula known under the name "exponential formula". It occurs quite naturally in many contexts (physics, mathematics, computer s…
Algebras of higher operads as enriched categories II
Michael Batanin, Denis-Charles Cisinski, Mark Weber
One of the open problems in higher category theory is the systematic construction of the higher dimensional analogues of the Gray tensor product. In this paper we continue the work…
On the density of systems of non-linear spatially homogeneous SPDEs
Eulalia Nualart
In this paper, we consider a system of second order non-linear stochastic partial differential equations with spatial dimension , driven by a -dimensional Gaussian…
Ladder Operators and Endomorphisms in Combinatorial Physics
Gérard Henry Edmond Duchamp, Laurent Poinsot, Allan I. Solomon +3
Starting with the Heisenberg-Weyl algebra, fundamental to quantum physics, we first show how the ordering of the non-commuting operators intrinsic to that algebra gives rise to gen…
Comment on "Superhard Semiconducting Optically Transparent High Pressure Phase of Boron"
A. R. Oganov, V. L. Solozhenko, O. O. Kurakevych +5
This Comment points out a number of errors in the recent paper by Zarechnaya, Dubrovinskaia, Dubrovinsky, et al. (Phys. Rev. Lett. 102, 185501 (2009)). Results and conclusions pres…
New high-pressure form of boron is significantly ionic
Artem R. Oganov, Jiuhua Chen, Carlo Gatti +7
The comment of Dubrovinskaia et al. is scientifically flawed. The high-pressure form of boron, discovered by Oganov et al., is indeed new and its bonding has a significant ionic ch…
High-resolution microwave frequency dissemination on an 86-km urban optical link
O. Lopez, A. Amy-Klein, M. Lours +2
We report the first demonstration of a long-distance ultra stable frequency dissemination in the microwave range. A 9.15 GHz signal is transferred through a 86-km urban optical lin…
Spectral shift function for operators with crossed magnetic and electric fields
Mouez Dimassi, Vesselin Petkov
We obtain a representation formula for the derivative of the spectral shift function related to the operators and $H(B, ε) = H_0…
Estimates on the speedup and slowdown for a diffusion in a drifted brownian potential
Gabriel Faraud
We study a model of diffusion in a brownian potential. This model was firstly introduced by T. Brox (1986) as a continuous time analogue of random walk in random environment. We es…
Two classes of algebras with infinite Hochschild homology
Andrea Solotar, Micheline Vigué-Poirrier
We prove without any assumption on the ground field that higher Hochschild homology groups do not vanish for two large classes of algebras whose global dimension in not finite.
Multifractal analysis of complex random cascades
Julien Barral, Xiong Jin
We achieve the multifractal analysis of a class of complex valued statistically self-similar continuous functions. For we use multifractal formalisms associated with pointwise osci…
