The optimal assignment problem for a countable state space

Marianne Akian, Stephane Gaubert, Vassili Kolokoltsov

Given a square matrix B=(b_{ij}) with real entries, the optimal assignment problem is to find a bijection s between the rows and the columns maximising the sum of the b_{is(i)}. In…

Two-scale semi-lagrangian simulation of a charged particle beam in a periodic focusing channel

Alexandre Mouton

This paper is devoted to numerical simulation of a charged particle beam submitted to a strong oscillating electric field. For that, we consider a two-scale numerical approach as f…

On the Almost Sure Central Limit Theorem for Vector Martingales: Convergence of Moments and Statistical Applications

Bernard Bercu, Peggy Cénac, Guy Fayolle

We investigate the almost sure asymptotic properties of vector martingale transforms. Assuming some appropriate regularity conditions both on the increasing process and on the mome…

Non-ergodicity of Nose-Hoover dynamics

Frederic Legoll, Mitchell Luskin, Richard Moeckel

The numerical integration of the Nose-Hoover dynamics gives a deterministic method that is used to sample the canonical Gibbs measure. The Nose-Hoover dynamics extends the physical…

A Sparse Flat Extension Theorem for Moment Matrices

Monique Laurent, Bernard Mourrain

In this note we prove a generalization of the flat extension theorem of Curto and Fialkow for truncated moment matrices. It applies to moment matrices indexed by an arbitrary set o…

Inference of Flow Statistics via Packet Sampling in the Internet

Yousra Chabchoub, Christine Fricker, Fabrice Guillemin +1

We show in this note that by deterministic packet sampling, the tail of the distribution of the original flow size can be obtained by rescaling that of the sampled flow size. To re…
