FROBENIUS–PERRON OPERATOR DESCRIPTION OF MARKOV CHAINS
Abstract: We consider canonical shift space representation of discrete-time Markov chain given
by transition kernels. Markov shifts and eigenfunctions of skew products above them are
characterized by terms of Frobenius–Perron operator. The results are applied to the exactness
property of Markov chains. We introduce also the notion of quasi-Markov chain and apply it
to Gauss endomorphisms.
