6. Random evolution and first-order hyperbolic PDE systems
In this final section, we show how random evolutions constructed from Markov jump processes provide a probabilistic representation of the solution of first-order hyperbolic PDE systems. We restrict ourselves to the simple case of jump processes with values in a finite set, and illustrate our results with an example related to the telegraph equation. At the cost of additional technical difficulties, it is possible to generalize these results to the case of jump processes with values in a non-countable set such as
