Francis Comets, Serguei Popov
We study branching random walks in random i.i.d. environment in . For this model, the population size cannot decrease, and a natural definition of recurrence is int…

Bindweeds or random walks in random environments on multiplexed trees and their asympotics
Mikhail Menshikov, Dimitri Petritis, Serguei Popov
We report on the asymptotic behaviour of a new model of random walk, we term the bindweed model, evolving in a random environment on an infinite multiplexed tree. The term \textit{…
