On the Markov property for nonlinear discrete-time systems with markovian inputs

The behavior of a general hybrid system in discrete-time can be represented by a non-linear difference equation x (k + 1) = F-k(x (k), theta(k)), where theta(k) is assumed to be a finite-state Markov chain. An important step in the stability analysis of these systems is to establish the Markov property of (x(k), theta(k)). There are, however, no complete proofs of this property which are simple to understand. This paper aims to correct this problem by presenting a complete and explicit proof, which uses only fundamental measure-theoretical concepts.
