    Title: Bresse‑Timoshenko type systems with thermodiffusioneffects: well‑possedness, stability and numerical results
    Abstract:

    Bresse-Timoshenko beam model with thermal, mass diffusion and theormoelastic effects is studied. We stated and proved the well-posedness of problem. The global existence and uniqueness of the solution is proved by using the classical Faedo-Galerkin approximationsalong with two a priori estimates. We proved an exponential stability estimate for problem under an unusual assumption, and by using a multiplier technique with frictional damping in the vertical displacement. Numerically, we constructed a numerical scheme based on the P1-finite element method for space discretization and implicit Euler scheme for time discre-tization. Then, we showed that the discrete energy decays, later a priori error estimates areestablished. Finally, some numerical simulations are presented.

    Title: Combinatorial optimization, issues and trends

    Abstract:

    Combinatorial optimization problems are used to model many situations in various domains of everyday life. For instance, one can look for a shortest route between two cities on a large road network or to scheduling exams for different courses at a university. In the last few decades, great progress has been made in this field of mathematics, allowing the development of efficient methods for solving complex and large-scale problems. These methods are based on convex optimization techniques, geometry, randomization, or are inspired by nature.

    In this talk, we will accurately describe this vast and rich field, discuss how to classify these problems according to their complexities, and the nuances behind this, and indicate some general limitations in solving most of these problems. We will also give some current trends for this.

    Titre de la participation: Modélisation mathématique de la dynamique épidémique des maladies transmissibles

     

    Résumé :

    L'émergence fréquente d’épidémies constitue un risque mondial de santé publique, qui nécessite le développement de politiques et de stratégies de lutte contre leur propagation. La modélisation mathématique est un outil incontournable pour comprendre la dynamique épidémique et l’évolution des maladies ransmissibles, elle permet d’établir plusieurs scénarios basés sur différentes hypothèses, différents paramètres et différentes données collectée. Un modèle épidémiologique bien conçu peut aider les gestionnaires de la santé publique à étudier l'impact de la maladie et concevoir des programmes efficaces de surveillance et de prévention.

    Dans cette présentation on expose quelques modèles classiques de maladies infectieuses, puis on aborde le développement et l’étude qualitative de la dynamique d’un modèle de tuberculose

    Title: Cohomologies and generalized derivations of n-Lie algebras.

     

    Abstract:

    In the present talk we shall introduce a cohomology theory for n-Lie algebras, which coincides with the existing cohomology theory only in the case n=3. We shall then show that this new cohomology theory is qualified to encompass the generalized derivations over n-Lie algebras as 1-cocycles, and the inner generalized derivations as 1-coboundaries.

    Title: Rota-Baxter operators : Dualization and Generalization

     

    Abstract:

    In this talk, we will discuss Rota-Baxter operators and their generalization on algebras and coalgebras. We  present a dual version of T. Brzezi\'{n}ski's results about Rota-Baxter systems which appeared  in 2016. Then as a generalization to bialgebras, we introduce the notion of Rota-Baxter bisystem  and construct various examples. On the other hand, we introduce  a new type of bialgebras (named mixed bialgebras) which are consisting of an associative algebra and a coassociative coalgebra satisfying the compatible condition determined by two coderivations. We investigate coquasitriangular mixed  bialgebras and the particular case of coquasitriangular infinitesimal bialgebras, where we give the double construction.

    Title: Finite time stability in fractional differential problems

     

    Abstract:

    In this presentation, we will explain what we mean by "finite stability" in our study. After exhibiting few examples in the integer-order case, we shall discuss the main difficulties encountered in the fractional case. Some suggestions are given to get around these difficulties.

    Title: On the numerical solutions of nonlinear quadratic integral equations of Urysohn type on the half-line

     

     

    Abstract: A numerical method for solving nonlinear quadratic integral equations of Urysohn type on the half-line is presented. This approach reduces the given equation to a systematic procedure by using a rational Legendre-collocation approximation (RLC). The rate of convergence and error analysis are provided. Moreover, some numerical examples are carried out to verify the spectral accuracy and the stability of the proposed method.

    Title: Local and Global Well-Posedness of a Coupled Westervelt-Pennes Model of Nonlinear Ultrasonic Heating

     

    Abstract: High-Intensity Focused Ultrasound (HIFU) waves are known to induce localized heat to a targeted area during medical treatments. In turn, the rise in temperature influences their speed of propagation. This coupling affects the position of the focal region as well as the achieved pressure and temperature values. In this work, we investigate a mathematical model of nonlinear ultrasonic heating based on the Westervelt wave equation coupled to the Pennes bioheat equation that captures this so-called thermal lensing effect. We prove that this quasi-linear model is well-posed locally and globally in time and does not degenerate under a smallness assumption on the pressure data. We also proved some decay estimates of the solution.
