Exact splitting methods for kinetic and Schr{ö}dinger equations
Joackim Bernier, Nicolas Crouseilles, Yingzhe Li
In [8], some exact splittings are proposed for inhomogeneous quadratic differential equations including, for example, transport equations, kinetic equations, and Schr{ö}dinger type…
Properties of Chromy's sampling procedure
Guillaume Chauvet
Chromy (1979) proposed a unequal probability sampling algorithm, which enables to select a sample in one pass of the sampling frame only. This is the default sequential method used…
Revisiting the asymptotics of the flow for some dynamical systems on the torus
Marc Briane, Loïc Hervé
In this paper we study the large time asymptotics of the flow of a dynamical system posed in the -dimensional torus. Rather than using the classical unique ergodicity…
Asymptotic behavior of orthogonal polynomials without the Carleman condition
Dmitri Yafaev
Our goal is to find an asymptotic behavior as of orthogonal polynomials defined by the Jacobi recurrence coefficients . We suppose that the of…
High order numerical schemes for transport equations on bounded domains
Benjamin Boutin, Thi Hoai Thuong Nguyen, Abraham Sylla +2
This article is an account of the NABUCO project achieved during the summer camp CEMRACS 2019 devoted to geophysical fluids and gravity flows. The goal is to construct finite diffe…
RAMESSES, a Rank Metric Encryption Scheme with Short Keys
Julien Lavauzelle, Pierre Loidreau, Ba-Duc Pham
We present a rank metric code-based encryption scheme with key and ciphertext sizes comparable to that of isogeny-based cryptography for an equivalent security level. The system al…
