Slipped non-Positive Reduced Dynamics and Entanglement
F. Benatti, R. Floreanini, S. Breteaux
Non-positive Markov approximations are sometimes used to describe the dynamics of qubits in weak interaction with suitable environments; the appearance of negative probabilities is…
Adaptive goodness-of-fit tests in a density model
Magalie Fromont, Béatrice Laurent
Given an i.i.d. sample drawn from a density , we propose to test that equals some prescribed density or that belongs to some translation/scale family. We introduce…
Experimental evidence of flow destabilization in a 2D bidisperse foam
Isabelle Cantat, Celine Poloni, Renaud Delannay
Liquid foam flows in a Hele-Shaw cell were investigated. The plug flow obtained for a monodisperse foam is strongly perturbed in the presence of bubbles whose size is larger than t…
Diffusion of a granular pulse in a rotating drum
Nicolas Taberlet, Patrick Richard
The diffusion of a pulse of small grains in an horizontal rotating drum is studied through discrete elements methods simulations. We present a theoretical analysis of the diffusion…
Differentiability of backward stochastic differential equations in Hilbert spaces with monotone generators
Philippe Briand, Fulvia Confortola
The aim of the present paper is to study the regularity properties of the solution of a backward stochastic differential equation with a monotone generator in infinite dimension. W…
