This paper provides deterministic approximation results for stochastic processes that arise when finite populations … recurrently play finite games. The deterministic approximation is defined in continuous time as a system of ordinary differential … stochastic process, for large populations, and its deterministic approximation. In particular, we show that if the deterministic …
