Fully spectral scheme for the linear BGK equation on the whole space
Bastien Grosse
In this article, we design a fully spectral method in both space and velocity for a linear inhomogeneous kinetic equation with mass, momentum and energy conservation. We focus on t…

Approximation by orthonormal polynomials associated with even exponential weights
Bastien Grosse
In this paper, we prove a quantitative approximation result by orthonormal polynomials associated to an exponential weight of the form e - , where is an even polynomial with…
