Multiple recurrence for two commuting transformations
Qing Chu
This paper is devoted to a study of the multiple recurrence of two commuting transformations. We derive a result which is similar but not identical to that of one single transforma…
Velocity and energy relaxation in two-phase flows
Yannick Meyapin, Denys Dutykh, Marguerite Gisclon
In the present study we investigate analytically the process of velocity and energy relaxation in two-phase flows. We begin our exposition by considering the so-called six equation…
A kinetic scheme for transient mixed flows in non uniform closed pipes: a global manner to upwind all the source terms
Christian Bourdarias, Mehmet Ersoy, Stéphane Gerbi
We present a numerical kinetic scheme for an unsteady mixed pressurised and free surface model. This model has a source term depending on both the space variable and the unknown, U…
Singular limit of a two-phase flow problem in porous medium as the air viscosity tends to zero
Robert Eymard, Marie Henry, Danielle Hilhorst
In this paper we consider a two-phase flow problem in porous media and study its singular limit as the viscosity of the air tends to zero; more precisely, we prove the convergence…
Air entrainment in transient flows in closed water pipes: a two-layer approach
Christian Bourdarias, Mehmet Ersoy, Stéphane Gerbi
In this paper, we first construct a model for free surface flows that takes into account the air entrainment by a system of four partial differential equations. We derive it by tak…
On the well-posedness of the incompressible density-dependent Euler equations in the framework
Raphaël Danchin
The present paper is devoted to the study of the well-posedness issue for the density-dependent Euler equations in the whole space. We establish local-in-time results for the Cauch…
Two-fluid barotropic models for powder-snow avalanche flows
Yannick Meyapin, Denys Dutykh, Marguerite Gisclon
In the present study we discuss several modeling issues of powder-snow avalanche flows. We take a two-fluid modeling paradigm. For the sake of simplicity, we will restrict our atte…
Strong Stability with respect to weak limit for a Hyperbolic System arising from Gas Chromatography
Christian Bourdarias, Marguerite Gisclon, Stéphane Junca
We investigate a system related to a particular isothermal gas-solid chromatography process, called ?Pressure Swing Adsorption?, with two species and instantaneous exchange kinetic…
Coherent and finiteness spaces
Pierre Hyvernat
This short note presents a new relation between coherent spaces and finiteness spaces. This takes the form of a functor from COH to FIN commuting with the additive and multiplicati…
Phase-space analysis and pseudodifferential calculus on the Heisenberg group
Hajer Bahouri, Clotilde Fermanian-Kammerer, Isabelle Gallagher
This paper has been withdrawn by the authors. A class of pseudodifferential operators on the Heisenberg group is defined. As it should be, this class is an algebra containing the c…
Geometrically rational real conic bundles and very transitive actions
Jérémy Blanc, Frédéric Mangolte
In this article we study the transitivity of the group of automorphisms of real algebraic surfaces. We characterize real algebraic surfaces with very transitive automorphism groups…
Mathematical modeling of powder-snow avalanche flows
Denys Dutykh, Céline Acary-Robert, Didier Bresch
Powder-snow avalanches are violent natural disasters which represent a major risk for infrastructures and populations in mountain regions. In this study we present a novel model fo…
