On the pointwise regularity of the Multifractional Brownian Motion and some extensions

Probability 2023-02-14 v1

Abstract

We study the pointwise regularity of the Multifractional Brownian Motion and in particular, we get the existence of slow points. It shows that a non self-similar process can still enjoy this property. We also consider various extensions of our results in the aim of requesting a weaker regularity assumption for the Hurst function without altering the regularity of the process.
