Hyperkahler manifolds from the Tits-Freudenthal square
Atanas Iliev, Laurent Manivel
We suggest a way to associate to each Lie algebra of type G2, D4, F4, E6, E7, E8 a family of polarized hyperkahler fourfolds, constructed as parametrizing certain families of cycle…
A Hamilton-Jacobi approach to characterize the evolutionary equilibria in heterogeneous environments
Sepideh Mirrahimi
In this work, we characterize the solution of a system of elliptic integro-differential equations describing a phenotypically structured population subject to mutation, selection a…
Coxeter element and particle masses
Laura Brillon, Vadim Schechtman
Let be a simple Lie algebra of rank over , a Cartan subalgebra. We construct a family of commuting Hermitian…
Cycles, derived categories, and rationality
Asher Auel, Marcello Bernardara
Our main goal is to give a sense of recent developments in the (stable) rationality problem from the point of view of unramified cohomology and 0-cycles as well as derived categori…
On the existence of fractional Brownian fields indexed by manifolds with closed geodesics
Nil Venet
We give a necessary condition of geometric nature for the existence of the -fractional Brownian field indexed by a Riemannian manifold. In the case of the Lévy Brownian field ($…
Center manifolds without a phase space
Gregory Faye, Arnd Scheel
We establish center manifold theorems that allow one to study the bifurcation of small solutions from a trivial state in systems of functional equations posed on the real line. The…
Topological aggregation, the twin paradox and the no show paradox
Guillaume Chèze
Consider the framework of topological aggregation introduced by Chichilnisky (1980). We prove that in this framework the Twin Paradox and the No Show Paradox cannot be avoided. Ano…
The Dichotomy for Conservative Constraint Satisfaction is Polynomially Decidable
Clément Carbonnel
Given a fixed constraint language , the conservative CSP over (denoted by c-CSP()) is a variant of CSP() where the domain of each variable can be restricted arbitraril…
Differential subordination under change of law
Komla Domelevo, Stefanie Petermichl
We prove optimal bounds for a pair of Hilbert space valued differentially subordinate martingales under a change of law. The change of law is given by a process called a we…
A new class of high order semi-Lagrangian schemes for rarefied gas dynamics
Giacomo Dimarco, Cory Hauck, Raphaël Loubère
In this paper we genealize the fast semi-Lagrangian scheme developed in [J. Comput. Phys., Vol. 255, 2013, pp 680-698] to the case of high order reconstructions of the distribution…
Exponential stability of a PI plus reset integrator controller by a sampled-data system approach
M. A. Davó, F. Gouaisbaut, A. Baños +2
The paper deals with the stability analysis of time-delay reset control systems, for which the resetting law is assumed to satisfy a time-dependent condition. A stability analysis…
On direct Arbitrary-Lagrangian-Eulerian ADER-WENO finite volume schemes for the HPR model of nonlinear hyperelasticity
Walter Boscheri, Michael Dumbser, Raphaël Loubère
This paper is concerned with the numerical solution of the unified first order hyperbolic formulation of continuum mechanics proposed by Peshkov & Romenski (HPR model), which is ba…
Effect of quantified irreducibility on the computability of subshift entropy
Silvère Gangloff, Benjamin Hellouin de Menibus
We study the difficulty of computing topological entropy of subshifts subjected to mixing restrictions. This problem is well-studied for multidimensional subshifts of finite type :…
Stability of point defects of degree in a two-dimensional nematic liquid crystal model
Radu Ignat, Luc Nguyen, Valeriy Slastikov +1
We study -radially symmetric solutions corresponding to topological defects of charge for integer in the Landau-de Gennes model describing liquid crysta…
Choquet-Monge-Ampere Classes
Vincent Guedj, Sibel Sahin, Ahmed Zeriahi
We introduce and study Choquet-Monge-Ampere classes on compact Kahler manifolds. They consist of quasi-plurisubharmonic functions whose sublevel sets have small enough asymptotic M…
