Description
The aim of this conference is to gather international experts and young researchers working on numerical analysis and scientific computing. Numerical methods and algorithms are essential in the approximate solution of many problems in theoretical and applied physics and chemistry, in data science and other branches of sciences, and in engineering. The design of effective algorithms plays an essential role in the success of these methods, in particular for large-scale computations. Scientific computing is mostly concerned with the implementation of numerical algorithms on various types of computer’s architectures. The writing of packages of routines for the public domain is a part of numerical analysis. The conference will cover the main topics related to numerical methods and scientific computing with a particular emphasis on numerical linear algebra, approximation theory, sparse approximation, network analysis, extrapolation and convergence acceleration, solution of nonlinear equations, orthogonal polynomials and quadrature, Padé approximation and continued fractions, inverse problems and regularization, software production and computer implementation, numerical stability and rounding errors. The fact that all these topics have interactions together and many applications in the solution of applied mathematics problems makes the conference interdisciplinary. A session on the history of mathematics will also be organized.
Le but de cette conférence est de rassembler des experts internationaux et de jeunes chercheurs travaillant en analyse numérique et en calcul scientifique. Les méthodes numériques et les algorithmes sont essentiels dans la résolution approchée de nombreux problèmes en physique et en chimie théorique et appliquée, en sciences des données et autres branches des sciences, et en ingénieurie. La conception d’algorithmes efficaces joue un rôle essentiel dans le succès de ces méthodes, en particulier pour les grands calculs. Le calcul scientifique est principalement concerné par la mise en œuvre d’algorithmes numériques sur différents types d’architectures d’ordinateurs. L’écriture de bibliothèques de programmes pour le domaine public fait partie de l’analyse numérique. La conférence couvrira les principaux sujets liés aux méthodes numériques et au calcul scientifique, en mettant un accent particulier sur l’algèbre linéaire numérique, la théorie de l’approximation, l’approximation parcimonieuse, l’analyse des réseaux, l’extrapolation et l’accélération de la convergence, la résolution d’équations non linéaires, les polynômes orthogonaux et les quadratures, l’approximation de Padé et les fractions continues, les probèmes inverses et la régularisation, la production de logiciels et leur implémentation informatique, la stabilité numérique et les erreurs d’arrondi. Le fait que tous ces sujets aient des interactions entre eux ainsi que de nombreuses applications dans la résolution de problèmes de mathématiques appliquées rend la conférence interdisciplinaire. Une session sur l’histoire des
mathématiques sera également organisée.
