This book is devoted to a number of stochastic models that display scale invariance. It
primarily focuses on three issues: probabilistic properties statistical estimation and
simulation of the processes considered. It will be of interest to probability specialists who
will find here an uncomplicated presentation of statistics tools and to those statisticians who
wants to tackle the most recent theories in probability in order to develop Central Limit
Theorems in this context both groups will also benefit from the section on simulation.
Algorithms are described in great detail with a focus on procedures that is not usually found
in mathematical treatises. The models studied are fractional Brownian motions and processes
that derive from them through stochastic differential equations. Concerning the proofs of the
limit theorems the Fourth Moment Theorem is systematically used as it produces rapid and
helpful proofs that can serve as models for the future. Readers will also find elegant and new
proofs for almost sure convergence. The use of diffusion models driven by fractional noise has
been popular for more than two decades now. This popularity is due both to the mathematics
itself and to its fields of application. With regard to the latter fractional models are
useful for modeling real-life events such as value assets in financial markets chaos in
quantum physics river flows through time irregular images weather events and contaminant
diffusion problems.
