The time-harmonic Maxwell equations with impedance boundary conditions in convex polyhedral domains

Serge Nicaise, Jérôme Tomezyk

In this paper, we first develop a variational formulation of the time-harmonic Maxwell equations with impedance boundary conditions in polyhedral domains similar to the one for domains with smooth boundary proposed in [12, §4.5.d]. It turns out that the variational space is embedded in H 1 as soon…

Crosslinking chemistry of poly(vinylmethyl-<i>co</i>-methyl)silazanes toward low-temperature formable preceramic polymers as precursors of functional aluminium-modified Si–C–N ceramics

Diane Fonblanc, David Lopez-Ferber, Mélanie Wynn, Abhijeet Lale, Anne Soleilhavoup, Anne Leriche, Yuji Iwamoto, Fabrice Rossignol, Christel Gervais, Samuel Bernard

Crosslinking chemistry of a liquid poly(vinylmethyl-co-methyl)silazane with an alane hydride-based complex according to Si : Al ratios varying from 5 to 2.5 has been investigated in detail through the characterization of the as-obtained polymers using solid-state NMR, FT-IR and elemental analyses.…

On the consensus tracking investigation for multi-agent systems on time scale via matrix-valued Lyapunov functions

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

This paper is devoted to the leader–follower consensus problem for high-order multi-agent systems with inherent nonlinear dynamics evolving on an arbitrary time domain. This problem is investigated using the time scale theory. Based on this theory, some sufficient conditions are derived to…

Distributed leader-follower consensus for a class of semilinear second order multi-agent systems using time scale theory

Serhii Babenko, Michael Defoort, Mohamed Djemai, Serge Nicaise

The problem of distributed leader‐follower consensus for second‐order linear multiagent systems with unknown nonlinear inherent dynamics is investigated in this paper. It is assumed that the dynamic of each agent is described by a semilinear second‐order dynamic equation on an arbitrary time scale…

Computer Vision viewing over Mathematics

Jean-Charles Canonne, Eric Cartignies, Jean-Paul Becar, Laurent Vermeiren, Abdelmalik Taleb-Ahmed, Yassin El Hillali

The difference between having images of something and having a knowledge of the same thing has been a subject of reflection for centuries, and some of the most important Greek tragedies focused on that point. A great part of infor-mation now consists of images: image has become the language of many…

Sharp phase transition for the continuum Widom-Rowlinson model

David Dereudre, Pierre Houdebert

The Widom-Rowlinson model (or the Area-interaction model) is a Gibbs point process in $\mathbb{R}^d$ with the formal Hamiltonian $H(\omega)=\text{Volume}(\cup_{x\in\omega} B_1(x))$, where $\omega$ is a locally finite configuration of points and $B_1(x)$ denotes the unit closed ball centred at $x$.…

Drinfeld–Sokolov reduction in quantum algebras: canonical form of generating matrices

Dimitri Gurevich, Pavel Saponov, Dmitry Talalaev

We define the second canonical forms for the generating matrices of the Reflection Equation algebras and the braided Yangians, associated with all even skew-invertible involutive and Hecke symmetries. By using the Cayley–Hamilton identities for these matrices, we show that they are similar to their…

The radiative transfer equation with a nonhomogeneous reflectivity boundary condition coupled with the heat conduction equation

Luc Paquet, Hawraa Nabolsi

In this paper, we make a rigorous mathematical analysis of the radiative heating of a semitransparent body made of a glass by a black radiative source surrounding it. This requires the study of the coupling between quasi‐steady radiative‐transfer boundary value problems with nonhomogeneous…
