Exponential decay for solutions to semilinear damped wave equation
Stéphane Gerbi, Belkacem Said-Houari
This paper is concerned with decay estimate of solutions to the semilinear wave equation with strong damping in a bounded domain. Introducing an appropriate Lyaponuv function, we p…
A model for unsteady mixed flows in non uniform closed water pipes and a well-balanced finite volume scheme
Christian Bourdarias, Mehmet Ersoy, Stéphane Gerbi
We present the derivation of a new unidirectional model for We present the derivation of a new unidirectional model for unsteady mixed flows in non uniform closed water pipes. We i…
Convergence of multiple ergodic averages along cubes for several commuting transformations
Qing Chu
We prove the norm convergence of multiple ergodic averages along cubes for several commuting transformations, and derive corresponding combinatorial results. The method we use reli…
Asymptotic stability and blow up for a semilinear damped wave equation with dynamic boundary conditions
Stéphane Gerbi, Belkacem Said-Houari
In this paper we consider a multi-dimensional wave equation with dynamic boundary conditions, related to the Kelvin-Voigt damping. Global existence and asymptotic stability of solu…
Spectrum of large random reversible Markov chains: two examples
Charles Bordenave, Pietro Caputo, Djalil Chafai
We take on a Random Matrix theory viewpoint to study the spectrum of certain reversible Markov chains in random environment. As the number of states tends to infinity, we consider…
Group and phase velocities in the free-surface visco-potential flow: new kind of boundary layer induced instability
Denys Dutykh
Water wave propagation can be attenuated by various physical mechanisms. One of the main sources of wave energy dissipation lies in boundary layers. The present work is entirely de…
Fefferman-Stein inequalities for the \mathbb{Z}_2^d Dunkl maximal operator
Luc Deleaval
In this article, we establish the Fefferman-Stein inequalities for the Dunkl maximal operator associated with a finite reflection group generated by the sign changes. Similar resul…
Global Existence Results for the Anisotropic Boussinesq System in Dimension Two
Raphaël Danchin, Marius Paicu
We study the global existence issue for the two-dimensional Boussinesq system with horizontal viscosity in only one equation. We first examine the case where the Navier-Stokes equa…
Influence of sedimentary layering on tsunami generation
Denys Dutykh, Frédéric Dias
The present article is devoted to the influence of sediment layers on the process of tsunami generation. The main scope here is to demonstrate and especially quantify the effect of…
A two-fluid model for violent aerated flows
Frédéric Dias, Denys Dutykh, Jean-Michel Ghidaglia
In the study of ocean wave impact on structures, one often uses Froude scaling since the dominant force is gravity. However the presence of trapped or entrained air in the water ca…
A compressible two-fluid model for the finite volume simulation of violent aerated flows. Analytical properties and numerical results
Frédéric Dias, Denys Dutykh, Jean-Michel Ghidaglia
In the study of ocean wave impact on structures, one often uses Froude scaling since the dominant force is gravity. However the presence of trapped or entrained air in the water ca…
On multifractality and time subordination for continuous functions
Stephane Seuret
We show that if is "homogeneously multifractal" (in a sense we precisely define), then is the composition of a monofractal function with a time subordinator (i.e. $…
Hilbert geometry for convex polygonal domains
Bruno Colbois, Constantin Vernicos, Patrick Verovic
We prove in this paper that the Hilbert geometry associated with an open convex polygonal set is Lipschitz equivalent to Euclidean plane.
Visco-potential free-surface flows and long wave modelling
Denys Dutykh
In a recent study [DutykhDias2007] we presented a novel visco-potential free surface flows formulation. The governing equations contain local and nonlocal dissipative terms. From p…
Real singular Del Pezzo surfaces and 3-folds fibred by rational curves, II
Fabrizio Catanese, Frederic Mangolte
Let W -> X be a real smooth projective 3-fold fibred by rational curves. J. Kollár proved that, if W(R) is orientable, then a connected component N of W(R) is essentially either a…
