The jumps are steered by a jump intensity function, allowing the jump times to depend on the current state of the process, and a jump measure, determining the distribution of the destination of the random jumps. We will henceforth call these piecewise deterministic processes or pdps. If not, is there something in the definition of a markov chain besides the fact that it is a random process based on which it can be shown that this process is not markov.
