Equivalent descriptions of perturbed Markov processes

Perturbation models as described in detail by Syski [9] are investigated from the point of view of transformations of time or of state. We consider whether the perturbed Markov process is equivalent to a state or time transformation of a process similar to the unperturbed one. Ways of ensuring such equivalences are discussed and a brief look at perturbations for continuous parameter, continuous state space processes is also taken.
