“Random walks in random sceneries and related models”
Venerdì 16 Giugno 2023, ore 14:30 - Aula 2BC30 - Françoise Pène (Université de Brest)
Abstract
I will present random walks in random sceneries (RWRS) as well as the following related models: U-statistics indexed by random walks, a model (by Matheron & de Marsily) of stratified media with inhomogeneous layers (random one-way streets) and the one-dimensional Lévy-Lorentz gas (random roundabouts on a line). I will present in particular results obtained in collaboration with Fabienne Castell, Nadine Guillotin-Plantard & Bruno Schapira (RWRS and stratified model), with Brice Franke & Martin Wendler (U-statistics), with Frank Aurzada (persistence), with Alessandra Bianchi and Marco Lenci (Lévy-Lorentz gas).
