Seneta-Heyde norming for branching random walks with -stable spine
Pierre Boutaud, Pascal Maillard
We consider branching random walks with a spine in the domain of attraction of an -stable Lévy process. For this process, the classical derivative martingale in general degenera…

A revisited proof of the Seneta-Heyde norming for branching random walks under optimal assumptions
Pierre Boutaud, Pascal Maillard
We introduce a set of tools which simplify and streamline the proofs of limit theorems concerning near-critical particles in branching random walks under optimal assumptions. We ex…
