On the local times of noise reinforced Bessel processes

Abstract

We investigate the effects of noise reinforcement on a Bessel process of dimension d(0,2)d\in(0,2), and more specifically on the asymptotic behavior of its additive functionals. This leads us to introduce a local time process and its inverse. We identify the latter as an increasing self-similar (time-homogeneous) Markov process, and from this, several explicit results can be deduced.
