Random skew plane partitions with a piecewise periodic back wall
Cedric Boutillier, Sevak Mkrtchyan, Nicolai Reshetikhin +1
Random skew plane partitions of large size distributed according to an appropriately scaled Schur process develop limit shapes. In the present work we consider the limit of large r…
A Geometric Proof of Calibration
Shie Mannor, Gilles Stoltz
We provide yet another proof of the existence of calibrated forecasters; it has two merits. First, it is valid for an arbitrary finite number of outcomes. Second, it is short and s…
Enlarging the functional space of decay estimates on semigroups
Clément Mouhot
This note briefly presents a new method for enlarging the functional space of a "spectral-gap-like" estimate of exponential decay on a semigroup. A particular case of the method wa…
Some applications of duality for Lévy processes in a half-line
Jean Bertoin, Mladen Savov
The central result of this paper is an analytic duality relation for real-valued Lévy processes killed upon exiting a half-line. By Nagasawa's theorem, this yields a remarkable tim…
Fractional Poincaré inequalities for general measures
Clément Mouhot, Emmanuel Russ, Yannick Sire
We prove a fractional version of Poincaré inequalities in the context of endowed with a fairly general measure. Namely we prove a control of an norm by a non local qua…
Vanishing Hachtroudi curvature and local equivalence to the Heisenberg sphere
Joel Merker
To any completely integrable second-order system of real or complex partial differential equations in n > 1 independent variables and in one dependent variable, Mohsen Hachtroudi a…
Le théorème de Bertini en famille
Olivier Benoist
We give upper bounds for the dimension of the set of hypersurfaces of whose intersection with a fixed integral projective variety is not integral. Our upper bounds a…
Typical points for one-parameter families of piecewise expanding maps of the interval
Daniel Schnellmann
Let be an interval and , , a one-parameter family of piecewise expanding maps such that for each the map admits a uni…
Subgraphs of weakly quasi-random oriented graphs
Omid Amini, Simon Griffiths, Florian Huc
It is an intriguing question to see what kind of information on the structure of an oriented graph one can obtain if does not contain a fixed oriented graph as a subgra…
Groupe de Brauer et points entiers de deux familles de surfaces cubiques affines
Jean-Louis Colliot-Thélène, Olivier Wittenberg
Let a be a nonzero integer. If a is not congruent to 4 or 5 modulo 9 then there is no Brauer-Manin obstruction to the existence of integers x, y, z such that x^3+y^3+z^3=a. In addi…
Current large deviations in a driven dissipative model
T. Bodineau, M. Lagouge
We consider lattice gas diffusive dynamics with creation-annihilation in the bulk and maintained out of equilibrium by two reservoirs at the boundaries. This stochastic particle sy…
On the confinement of a tokamak plasma
Daniel Han-Kwan
The goal of this paper is to understand from a mathematical point of view the magnetic confinement of plasmas for fusion. Following Frénod and Sonnendrücker \cite{FS2}, we first us…
Existence and conservation laws for the Boltzmann-Fermi equation in a general domain
Thibaut Allemand
We prove an existence theorem for the Boltzmann-Fermi-Dirac equation for integrable collision kernels in possibly bounded domains with specular reflection at the boundaries, using…
Nonrigid spherical real analytic hypersurfaces in C^2
Joel Merker
A Levi nondegenerate real analytic hypersurface M of C^2 represented in local coordinates (z, w) in C^2 by a complex defining equation of the form w = Theta (z, \bar z, \bar w) whi…
Sophus Lie, Friedrich Engel and the Riemann-Helmholtz problem
Joel Merker
A focused modernization of Sophus Lie's brilliant writings about the foundations of geometry that every contemporary geometer should have at least once a look at. Translated, updat…
Automorphic Lefschetz properties via cohomology
Mathieu Cossutta
In this paper one proves a special case of a conjecture by Nicolas Bergeron. This conjecture is a kind of automorphic Lefschetz property. It relates the primitive cohomology of a l…
High confidence estimates of the mean of heavy-tailed real random variables
Olivier Catoni
We present new estimators of the mean of a real valued random variable, based on PAC-Bayesian iterative truncation. We analyze the non-asymptotic minimax properties of the deviatio…
Theta lifting for some cohomologicaly induced representations
Mathieu Cossutta
In his paper 'Theta lifting for representations with non zero cohomlogy', Jian-Shu Li proved that a certain kind of cohomological representations of is automorphic. In thi…
An effective version of a theorem of Kawamata on the Albanese map
Zhi Jiang
This paper is devoted to study the birational properties of the Albanese map. I generalize a theorem of Kawamata to tell when the Albanese map is surjective and when it is an algeb…
Sublinear variance for directed last-passage percolation
B. T. Graham
A range of first-passage percolation type models are believed to demonstrate the related properties of sublinear variance and superdiffusivity. We show that directed last-passage p…
Bridge Decomposition of Restriction Measures
Tom Alberts, Hugo Duminil-Copin
Motivated by Kesten's bridge decomposition for two-dimensional self-avoiding walks in the upper half plane, we show that the conjectured scaling limit of the half-plane SAW, the SL…
Compactification de Chabauty des espaces symétriques de type non compact
Thomas Haettel
The space of closed subgroups of a locally compact topological group is endowed with a natural topology, called the Chabauty topology. Let X be a symmetric space of noncompact type…
Adaptive density estimation: a curse of support?
Patricia Reynaud-Bouret, Vincent Rivoirard, Christine Tuleau-Malot
This paper deals with the classical problem of density estimation on the real line. Most of the existing papers devoted to minimax properties assume that the support of the underly…
Mathematical study of the -plane model for rotating fluids in a thin layer
Anne-Laure Dalibard, Laure Saint-Raymond
This article is concerned with an oceanographic model describing the asymptotic behaviour of a rapidly rotating and incompressible fluid with an inhomogeneous rotation vector; the…
