On Pareto theory of circulation of elites
Ricardo Pérez-Marco
We prove that Pareto theory of circulation of elites results from our wealth evolution model, Kelly criterion for optimal betting and Keynes' observation of "animal spirits" that d…
Grain Boundaries in Graphene on SiC(000) Substrate
Yann Tison, Jérôme Lagoute, Vincent Repain +7
Grain boundaries in epitaxial graphene on the SiC(000) substrate are studied using scanning tunneling microscopy and spectroscopy. All investigated small-angle grain bound…
Tackling the Limits of Optical Fiber Links
Fabio Stefani, Olivier Lopez, Anthony Bercy +5
We theoretically and experimentally investigate relevant noise processes arising in optical fiber links, which fundamentally limit their relative stability. We derive the unsuppres…
Quantum cascade laser frequency stabilisation at the sub-Hz level
Bérengère Argence, Bruno Chanteau, Olivier Lopez +7
Quantum Cascade Lasers (QCL) are increasingly being used to probe the mid-infrared "molecular fingerprint" region. This prompted efforts towards improving their spectral performanc…
Local times of subdiffusive biased walks on trees
Yueyun Hu
Consider a class of null-recurrent randomly biased walks on a super-critical Gaton-Watson tree. We obtain the rates of convergence of the local times and the quenched local probabi…
Sobolev spaces of maps and the Dirichlet problem for harmonic maps
Stefano Pigola, Giona Veronelli
In this paper we prove the existence of a solution to the Dirichlet problem for harmonic maps into a geodesic ball on which the squared distance function from the origin is strictl…
The non-hyperbolicity of irrational invariant curves for twist maps and all that follows
M. -C Arnaud, P Berger
The key result of this article is key lemma: if a Jordan curve is invariant by a given C 1+ -diffeomorphism f of a surface and if carries an ergodic hyperbolic probabili…
Magnetization reversal behavior in complex shaped Co nanowires: a nanomagnet morphology optimization
Fatih Zighem, Silvana Mercone
A systematic micromagnetic study of the morphological characteristic effects over the magnetic static properties of Co-based complex shaped nanowires is presented. The relevance of…
A chromium dipolar Fermi sea
B. Naylor, A. Reigue, E. Maréchal +3
We report on the production of a degenerate Fermi gas of 53Cr atoms, polarized in the state F=9/2, m_F=-9/2, by sympathetic cooling with bosonic S=3, m_S=-3 52Cr atoms. We load in…
Univariate Niho Bent Functions from o-Polynomials
Lilya Budaghyan, Alexander Kholosha, Claude Carlet +1
In this paper, we discover that any univariate Niho bent function is a sum of functions having the form of Leander-Kholosha bent functions with extra coefficients of the power term…
A priori estimates and bifurcation of solutions for a noncoercive elliptic equation with critical growth in the gradient
Philippe Souplet
We study nonnegative solutions of the boundary value problem $$-Δu = λc(x)u + μ(x)|\nabla u|^2 + h(x),\quad u\in H^1_0(Ω)\cap L^\infty(Ω), \leqno(P_λ)$$ where is a smooth bound…
The Jacobian Conjecture, a Reduction of the Degree to the Quadratic Case
A. de Goursac, A. Sportiello, A. Tanasa
The Jacobian Conjecture states that any locally invertible polynomial system in C^n is globally invertible with polynomial inverse. C. W. Bass et al. (1982) proved a reduction theo…
Generic family with robustly infinitely many sinks
Pierre Berger
We show, for every or , the existence of a Baire generic set of -families of -maps of a manifold of dimension , so…
On the interior motive of certain Shimura varieties: the case of Picard surfaces
J. Wildeshaus
The purpose of this article is to construct a Hecke-equivariant Chow motive whose realizations equal interior (or intersection) cohomology of Picard surfaces with regular algebraic…
Using graph transformation algorithms to generate natural language equivalents of icons expressing medical concepts
Pascal Vaillant, Jean-Baptiste Lamy
A graphical language addresses the need to communicate medical information in a synthetic way. Medical concepts are expressed by icons conveying fast visual information about patie…
Large values of cusp forms on GL(n)
Farrell Brumley, Nicolas Templier
We establish the transition behavior of Jacquet-Whittaker functions on split semi-simple Lie groups. As a consequence, we show that for certain finite volume Riemannian manifolds,…
Quadratic Zero-Difference Balanced Functions, APN Functions and Strongly Regular Graphs
Claude Carlet, Guang Gong, Yin Tan
Let be a function from to itself and a positive integer. is called zero-difference -balanced if the equation has exactly solut…
Revealing sub-μm inhomogeneities and μm-scale texture in H2O ice at Megabar pressures via sound velocity measurements by time-domain Brillouin scattering
Sergey M. Nikitin, Nikolay Chigarev, Vincent Tournat +5
Time-domain Brillouin scattering technique, also known as picosecond ultrasonic interferometry, which provides opportunity to monitor propagation of nanometers to sub-micrometers l…
The asymptotic diameter of cyclohedra
Lionel Pournin
It is shown here that the diameter of the -dimensional cyclohedron is not greater than . It is also shown that the coefficient in this upper bound is…
Blow-up results for a strongly perturbed semilinear heat equation: Theoretical analysis and numerical method
Van Tien Nguyen, Hatem Zaag
We consider a blow-up solution for a strongly perturbed semilinear heat equation with Sobolev subcritical power nonlinearity. Working in the framework of similarity variables, we f…
An analysis of the intermediate field theory of tensor model
Viet Anh Nguyen, Stephane Dartois, Bertrand Eynard
In this paper we analyze the multi-matrix model arising from the intermediate field representation of the tensor model with all quartic melonic interactions. We derive the saddle p…

J. Ducoulombier
We prove that if a pair of semi-cosimplicial spaces (X,Y) arise from a coloured operad then the semi-totalization sTot(Y) has the homotopy type of a relative double loop space and…
