They were four extroardinary women who read minds, healed bodies, diverted disasters, foretold the future--and became pariahs in their own land. A talented, elite cadre, they stepped out of the everyday human race...to enter their own!
This title considers the special of random processes known as semi-Markov processes. These possess the Markov property with respect to any intrinsic Markov time such as the first exit time from an open set or a finite iteration of these times. The class of semi-Markov processes includes strong Markov processes, Lévy and Smith stepped semi-Markov processes, and some other subclasses. Extensive coverage is devoted to non-Markovian semi-Markov processes with continuous trajectories and, in particular, to semi-Markov diffusion processes.
