This book deals with topics in the area of Lévy processes and infinitely
divisible distributions such as Ornstein-Uhlenbeck type processes,
selfsimilar additive processes and multivariate subordination. These
topics are developed around a decreasing chain of classes of
distributions Lm, m = 0,1, ...,∞, from the class
L0 of selfdecomposable distributions to the class
L∞ generated by stable distributions through convolution
and convergence.
The book is divided into five chapters. Chapter 1 studies basic
properties of Lm classes needed for the subsequent
chapters. Chapter 2 introduces Ornstein-Uhlenbeck type processes
generated by a Lévy process through stochastic integrals based on Lévy
processes. Necessary and sufficient conditions are given for a
generating Lévy process so that the OU type process has a limit
distribution of Lm class.
Chapter 3 establishes the correspondence between selfsimilar additive
processes and selfdecomposable distributions and makes a close
inspection of the Lamperti transformation, which transforms selfsimilar
additive processes and stationary type OU processes to each other.
Chapter 4 studies multivariate subordination of a cone-parameter Lévy
process by a cone-valued Lévy process. Finally, Chapter 5 studies
strictly stable and Lm properties inherited by the
subordinated process in multivariate subordination.
In this revised edition, new material is included on advances in these
topics. It is rewritten as self-contained as possible. Theorems, lemmas,
propositions, examples and remarks were reorganized; some were deleted
and others were newly added. The historical notes at the end of each
chapter were enlarged.
This book is addressed to graduate students and researchers in
probability and mathematical statistics who are interested in learning
more on Lévy processes and infinitely divisible distributions.
