On an SVD-based algorithm for identifying meta-stable states of Markov chains

Ryan M. Tifenbach


A Markov chain is a sequence of random variables $X = \{x_{t}\}$ that take on values in a state space $\mathcal{S}$. A meta-stable state with respect to $X$ is a collection of states $\mathcal{E} \subseteq \mathcal{S}$ such that transitions of the form $x_{t} \in \mathcal{E}$ and $x_{t+1} \notin \mathcal{E}$ are exceedingly rare. In Fritzsche et al. [Electron. Trans. Numer. Anal., 29 (2008), pp. 46–69], an algorithm is presented that attempts to construct the meta-stable states of a given Markov chain. We supplement the discussion contained therein concerning the two main results.
