Noise Reinforced Lévy Processes: Lévy-Itô Decomposition and Applications

Alejandro Rosales-Ortiz

A step reinforced random walk is a discrete time process with memory such that at each time step, with fixed probability $p \in (0, 1)$ , it repeats a previously performed step chose…

The structure of the local time of Markov processes indexed by Levy trees

Armand Riera, Alejandro Rosales-Ortiz

We construct the analogue of the local time -- at a fixed point $x$ -- for Markov processes indexed by Levy trees. We start by proving that Markov processes indexed by Levy trees s…
