Metastability of finite state Markov chains: a recursive procedure to identify slow variables for model reduction

C. Landim, T. Xu

Consider a sequence $({\eta }^N(t):t\ge 0)$ of continuous-time, irreducible Markov chains evolving on a fixed finite set $E$, indexed by a parameter $N$. Denote by $R_N(\eta ,\xi )$ the jump r…
