Distributed Markov Processes
Résumé
This paper introduces the model of Distributed Markov Processes (DMP), a probabilistic model of a system with distributed state over n>1 sites. The definition of DMP being given, the notion of stopping time in the distributed context is introduced, and a Strong Markov Property is derived. DMP are then characterized by their characteristic coefficients. These play a role similar to the coefficients of the transition matrix of discrete Markov chains, excepted that normalization conditions sufficient to define a DMP are not given here. The characteristic coefficients of a DMP are shown to satisfy the concurrency equations. The main result of the paper is the proof of the existence of DMP on n sites, n>1. The proof makes use of the tools introduced, especially the notion of stopping times. The case n=2 has been extensively studied in a previous note.
