A readily accessible introduction to the theory of stochastic processes
with emphasis on processes with independent increments and Markov
processes. After preliminaries on infinitely divisible distributions and
martingales, Chapter 1 gives a thorough treatment of the decomposition
of paths of processes with independent increments. Chapter 2 contains a
detailed treatment of time-homogeneous Markov processes from the
viewpoint of probability measures on path space. Two separate Sections
present about 70 exercises and their complete solutions. The text and
exercises are carefully edited and footnoted, while retaining the style
of the original lecture notes from Aarhus University.
