Homogenenous Multitype Fragmentations
Jean Bertoin
A homogeneous mass-fragmentation, as it has been defined in \cite{RFC}, describes the evolution of the collection of masses of fragments of an object which breaks down into pieces…
Existence of solutions of the hyperbolic Keller-Segel model
Benoit Perthame, Anne-Laure Dalibard
We are concerned with the hyperbolic Keller-Segel model with quorum sensing, a model describing the collective cell movement due to chemical signalling with a flux limitation for h…
Polar decomposition for p-adic symmetric spaces
Yves Benoist, Hee Oh
Let G be the group of k-points of a connected reductive k-group and H a symmetric subgroup associated to an involution s of G. We prove a polar decomposition G=KAH for the symmetri…
On the Inverse Problem for a Size-Structured Population Model
Benoit Perthame, Jorge P. Zubelli
We consider a size-structured model for cell division and address the question of determining the division (birth) rate from the measured stable size distribution of the population…
Real closed fields with nonstandard and standard analytic structure
Raf Cluckers, Leonard Lipshitz, Zachary Robinson
We consider the ordered field which is the completion of the Puiseux series field over \bR equipped with a ring of analytic functions on [-1,1]^n which contains the standard subana…
A geometrical proof of the Hartogs extension theorem
Joël Merker, Egmont Porten
100 years ago exactly, in 1906, Hartogs published a celebrated extension phenomenon (birth of Several Complex Variables), whose global counterpart was stated in full generality lat…
Finite complex reflection arrangements are K(pi,1)
David Bessis
Let be a finite dimensional complex vector space and $W\subseteq \GL(V)$ be a finite complex reflection group. Let $V^{\reg}$ be the complement in of the reflecting hyperpl…
Asymptotics for rooted planar maps and scaling limits of two-type spatial trees
Mathilde Weill
We prove some asymptotic results for the radius and the profile of large random bipartite planar maps. Using a bijection due to Bouttier, Di Francesco and Guitter between rooted bi…
Energy concentration and Sommerfeld condition for Helmholtz equation with variable index at infinity
Benoit Perthame, Luis Vega
We consider the Helmholtz equation with a variable index of refraction , which is not necessarily constant at infinity but can have an angular dependency like $n(x)\to n\_\in…
The topological structure of scaling limits of large planar maps
Jean-Francois Le Gall
We discuss scaling limits of large bipartite planar maps. If p is a fixed integer strictly greater than 1, we consider a random planar map M(n) which is uniformly distributed over…
Concentration for norms of infinitely divisible vectors with independent components
Christian Houdré, Philippe Marchal, Patricia Reynaud-Bouret
We obtain dimension-free concentration inequalities for -norms, , of infinitely divisible random vectors with independent coordinates and finite exponential moments…
Wall laws for fluid flows at a boundary with random roughness
Arnaud Basson, David Gerard-Varet
The general concern of this paper is the effect of rough boundaries on fluids. We consider a stationary flow, governed by incompressible Navier-Stokes equations, in an infinite dom…
Remarks on Boundary Layer Expansions
David Gerard-Varet, Thierry Paul
A systematic mathematical methodology for derivation of boundary layer expansions is presented. An explicit calculation of boundary layer sizes is given and proved to be coordinate…
Projective Pseudodifferential Analysis and Harmonic Analysis
Michael Pevzner, André Unterberger
We consider pseudodifferential operators on functions on which commute with the Euler operator, and can thus be restricted to spaces of functions homogeneous of some giv…
Sur la compactification de Thurston de l'espace de Teichmüller
Frédéric Paulin
The aim of these lecture notes is, after having quickly described various compactifications of the Teichmüller space of a compact connected oriented surface minus finitely many poi…
Improved Second-Order Bounds for Prediction with Expert Advice
Nicolo Cesa-Bianchi, Yishay Mansour, Gilles Stoltz
This work studies external regret in sequential prediction games with both positive and negative payoffs. External regret measures the difference between the payoff obtained by the…
Motivic cohomology of the complement of hyperplane arrangements
A. Chatzistamatiou
We give a presentation of the motivic cohomology ring of the complement of a hyperplane arrangement considered as algebra over the motivic cohomology of the ground field.
On the 3-distortion of a path
Pierre Dehornoy
We prove that, when a path of length n is embedded in R^2, the 3-distortion is an Omega(n^{1/2}), and that, when embedded in R^d, the 3-distortion is an O(n^{1/d-1}).
