ABSTRACT
The empirical distributions of an increasing number of i.i.d. continuous-time finite-state Markov processes at a finite number of time points satisfy a large deviation principle. Similarly the cumulative state occupation time distributions for these time points satisfy a large deviation principle. In this work we analyze the rate function which arises in a combination of these large deviation principles. We obtain an explicit characterization for its finiteness and a representation of its finite values by finite solutions of convex minimization problems.
