Entropy of absorbed Markov chains

Probability 2019-10-03 v1

Abstract

We consider a strictly substochastic matrix or an stochastic matrix with absorbing states. By using quasi-stationary distributions one shows there is a canonical associated stationary Markov chain. Based upon 22-stringing representation of the resurrected chain we supply a stationary representation of the killed and the absorbed chains. The entropies of these representations has a clear meaning when one identifies the probability measure of natural factors. The balance between the entropies of these representations and the canonical chain, serves to check the suitability of the whole construction.
