A Lloyd-stabilized Voronoi particle method
Bruno Després, Borjan Geshkovski
We study the stability and consistency of Lloyd's algorithm used in combination with the Lagrangian transport of a density on a Voronoï tessellation. We show that relaxation rates…
A projection algorithm on the set of polynomials with two bounds
Martin Campos Pinto, Frédérique Charles, Bruno Després +1
The motivation of this work stems from the numerical approximation of bounded functions by polynomials satisfying the same bounds. The present contribution makes use of the recent…
Computation of sum of squares polynomials from data points
Bruno Després, Maxime Herda
We propose an iterative algorithm for the numerical computation of sums of squares of polynomials approximating given data at prescribed interpolation points. The method is based o…
Sharpening methods for finite volume schemes
B Després, S Kokh, Frédéric Lagoutière
We review sharpening methods for finite volume schemes, with an emphasis on the basic structure of sharpening methods. It covers high order methods and non linear techniques for li…
Asymptotic preserving schemes on distorted meshes for Friedrichs systems with sti relaxation: application to angular models in linear transport
Christophe Buet, Bruno Després, Emmanuel Franck
In this paper we propose an asymptotic preserving scheme for a family of Friedrichs systems on unstructured meshes based on a decomposition between the hyperbolic heat equation and…
