On generalized principal eigenvalues of nonlocal operators with a drift *
Jérôme Coville, Francois Hamel
This article is concerned with the following spectral problem: to find a positive function C 1 () and R such that q(x) (x) + ^ J(x, y)(y) dy + a(x)…
Trotter-Kato product formulae in Dixmier ideal
Valentin Zagrebnov
It is shown that for a certain class of the Kato functions the Trotter-Kato product formulae converge in Dixmier ideal C 1, in topology, which is defined by the 1,…
The diameter and the Traversale : inside Girard Desargues' workshop
Marie Anglade, Jean-Yves Briend
In his \textit{Brouillon Project} on conic sections, Girard Desargues studies the notion of \textit{traversale}, which generalizes that of diameter introduced by Apollonius. One of…
Frank-Wolfe Algorithm for the Exact Sparse Problem
Farah Cherfaoui, Valentin Emiya, Liva Ralaivola +1
In this paper, we study the properties of the Frank-Wolfe algorithm to solve the \ExactSparse reconstruction problem. We prove that when the dictionary is quasi-incoherent, at each…
Decomposition, purity and fibrations by normal crossing divisors
Fouad El Zein, Dung Trang Lê, Xuanming Ye
We give a simple geometric proof of the decomposition theorem in terms of Thom-Whitney stratifications by reduction to fibrations by normal crossings divisors over the strata and e…
Normal distribution of correlation measures of binary sum-of-digits functions
Jordan Emme, Pascal Hubert
In this paper we study correlation measures introduced in \cite{emme_asymptotic_2017}. Denote by the asymptotic density of the set $\mathcal{E}_{a,d}=\{n \in \mathbb{N}, \…
Surface shear waves in a half-plane with depth-variant structure
Andrey Sarychev, Alexander Shuvalov, Marco Spadini
We consider the propagation of surface shear waves in a half-plane, whose shear modulus and density depend continuously on the depth coordinate . The problem amoun…
Extension of Discrete Mechanics towards Electromagnetism
Jean-Paul Caltagirone
The attempt to unify the laws of physics is approached from a discrete vision of space and time, abandoning the continuous medium paradigm that presided over the derivation of cert…
Bisymplectic Grassmannians of planes
Vladimiro Benedetti
The bisymplectic Grassmannian IGr parametrizes k-dimensional subspaces of a vector space V which are isotropic with respect to two general skew-symmetric forms; it is a…
Fonctions arithmétiques multiplicativement monotones
Michel Balazard
A real arithmetic function f is multiplicatively monotonous if f (mn) -- f (m) has constant sign for m, n positive integers. Properties and examples of such functions are discussed…
Undecidable word problem in subshift automorphism groups
Pierre Guillon, Emmanuel Jeandel, Jarkko Kari +1
This article studies the complexity of the word problem in groups of automorphisms of subshifts. We show in particular that for any Turing degree, there exists a subshift whose aut…
Finite element method with local damage on the mesh
Michel Duprez, Vanessa Lleras, Alexei Lozinski
We consider the finite element method on locally damaged meshes allowing for some distorted cells which are isolated from one another. In the case of the Poisson equation and piece…
The generic limit set of cellular automata
Saliha Djenaoui, Pierre Guillon
In this article, we consider a topological dynamical system. The generic limit set is the smallest closed subset which has a comeager realm of attraction. We study some of its topo…
Space-Time Extension of the MEM Approach for Electromagnetic Neuroimaging
Marie-Christine Roubaud, Jean-Marc Lina, Julie Carrier +1
The wavelet Maximum Entropy on the Mean (wMEM) approach to the MEG inverse problem is revisited and extended to infer brain activity from full space-time data. The resulting dimens…
Sur certaines équations fonctionnelles approchées, liées à la transformation de Gauss
Michel Balazard, Bruno Martin
In the line of classical work by Hardy, Littlewood and Wilton, we study a class of functional equations involving the Gauss transformation from the theory of continued fractions. T…
Willis metamaterial on a structured beam
Yongquan Liu, Zixian Liang, Jian Zhu +5
Bianisotropy is common in electromagnetics whenever a cross-coupling between electric and magnetic responses exists. However, the analogous concept for elastic waves in solids, ter…
On soft capacities, quasi-stationary distributions and the pathwise approach to metastability
Alexandre Gaudilliere, A. Bianchi, P Milanesi
Motivated by the study of the metastable stochastic Ising model at subcritical temperature and in the limit of a vanishing magnetic field, we extend the notion of (, )-capaci…
Exponential rate for the contact process extinction time
Bruno Schapira, Daniel Valesin
We consider the extinction time of the contact process on increasing sequences of finite graphs obtained from a variety of random graph models. Under the assumption that the infect…
Low Mach number limit of some staggered schemes for compressible barotropic flows
R. Herbin, J. -C Latché, Khaled Saleh
In this paper, we study the behaviour at low Mach number of numerical schemes based on staggered discretizations for the barotropic Navier-Stokes equations. Three time discretizati…
L'usage de la combinatoire chez Girard Desargues : le cas du théorème de Ménélaüs
Jean-Yves Briend, Marie Anglade
We show in this article how Girard Desargues, in his well known text on conics, the \textit{Brouillon Project,} manages to use Menelaos' theorem with some awesome virtuosity. To th…
Analysis of the Robustness of Conventional and Topologically Protected Edge States in Phononic Crystal Plates
Yabin Jin, Daniel Torrent, Bahram Djafari-Rouhani
In this work we theoretically study the interface acoustic states of resonators on a thin plate with topologically protected and conventional designs. Topologically protected inter…
Distribution of the absolute indicator of random Boolean functions
Florian Caullery, François Rodier
The absolute indicator is one of the measures used to determine the resistance offered by a Boolean function when used in the design of a symmetric cryptosystem. It was proposed al…
A notion of stability for k-means clustering
Thibaut Le Gouic, Quentin Paris
In this paper, we define and study a new notion of stability for the -means clustering scheme building upon the notion of quantization of a probability measure. We connect this…
