A vectorial lattice Boltzmann scheme for the incompressible Navier-Stokes equations

Denise Aregba-Driollet, Thomas Bellotti, Roberto Natalini +1

We introduce a second-order accurate vectorial lattice Boltzmann scheme for the incompressible Navier-Stokes system, inspired by a discrete-velocity kinetic approximation proposed…

Analysis and structure-preserving discretization of the Heat-GLM system

Firas Dhaouadi, Laura Río-Martín, Laura R{í}o-Mart{í}n +1

In this paper, we study a prototype hyperbolic system arising from the coupling of Generalized-Lagrangian-Multiplier (GLM) curl-cleaning with linear acoustics. We first show that,…

Convergence of a two-relaxation-times kinetic approximation towards the solution of a scalar conservation law

Denise Aregba-Driollet, Thomas Bellotti

We introduce a two-relaxation-times (TRT) kinetic approximation for scalar non-linear conservation laws in one space dimension, addressing the convergence of relaxation approximati…

Stability of the Active Flux Method in the Framework of Summation-by-Parts Operators

Wasilij Barsukow, Christian Klingenberg, Lisa Lechner +3

The Active Flux method is a numerical method for conservation laws using a combination of cell averages and point values as independent degrees of freedom, based on ideas from fini…

A Database of Continued Fractions of Polynomial Type

Henri Cohen

We describe a database of 1883 continued fractions with polynomial coefficients, of which more than 1600 are new, both for interesting constants and for transcendental functions, a…

Markovian dynamics of single-rebit open quantum systems with applications to colour perception

Michel Berthier, Gabriel Niebel, Edoardo Provenzi

This paper investigates the Markovian dynamics of open two-state quantum systems defined over the real numbers (rebits). Two main objectives are pursued. First, we present a compre…
