This advanced text explores the relationship between Markov processes and potential theory, in addition to aspects of the theory of additive functionals. Geared toward graduate students, "Markov Processes and Potential Theory" assumes a familiarity with general measure theory, while offering a nearly self-contained treatment.
Topics include Markov processes, excessive functions, multiplicative functionals and subprocesses, and additive functionals and their potentials. A concluding chapter examines dual processes and potential theory. Exercises appear throughout the text, and a selection...

DNA methylation is essential for the normal development and functioning of organisms. This volume discusses the latest developments in this very active field of research. It presents the evolution of DNA methylation, mammalian DNA methyltransferases, DNA methylation and demethlyation, DNA methylation and silencing and the role it plays in medicine including cancer.

Let {Xti t O} be a Markov process in Rl, and break up the path X t into (random) component pieces consisting of the zero set ({ tlX = O}) and t the "excursions away from 0," that is pieces of path X.: T::5 s::5 t, with Xr- = X = 0, but X. 1= 0 for T
