Analysis of hidden Markov models states generated by special jump processes

This paper investigates a class of stochastic differential systems with random structure, the transitions of which are generated by the special Markov jump processes. A statement concerning the Markovian property of the couple “jump process–governed diffusion” is presented. An analogue of the Fokker–Plank–Kolmogorov equation in the form of a system of partial integrodifferential equations, describing the evolution of the mutual transition probability of this couple, is derived.
