Abstract

This thesis focuses on the fractional Brownian motion (fBM), a stochastic process used to model long-memory phenomena using the Hurst parameter (H). It explores the mathematical properties of fBM, introduces methods to simulate its paths and estimate the H parameter, with applications in finance, hydrology, and biology.
