What is… a reinforced elephant random walk?

Vortrag von Chen Jiaming

Datum: 07.03.23  Zeit: 16.15 - 18.30  Raum:

The elephant random walk (ERW) is a self-reinforced discrete-time process on multidimensional lattice which was introduced in the early 2000s by Schütz and Trimper in order to study how long-range memory affects the behavior of the random walk. In this talk, I will present the reinforcement mechanism and how martingale theory can be used to obtain results on the asymptotic behavior of the ERW, as well as some of its related processes (barycenter, moderate Cramér deviation…).
