# Chains with Complete Connections: General Theory, Uniqueness, Loss of Memory and Mixing Properties

@article{Fernndez2003ChainsWC, title={Chains with Complete Connections: General Theory, Uniqueness, Loss of Memory and Mixing Properties}, author={Roberto Fern{\'a}ndez and Gr'egory Maillard}, journal={Journal of Statistical Physics}, year={2003}, volume={118}, pages={555-588} }

We introduce a statistical mechanical formalism for the study of discrete-time stochastic processes with which we prove: (i) General properties of extremal chains, including triviality on the tail σ-algebra, short-range correlations, realization via infinite-volume limits and ergodicity. (ii) Two new sufficient conditions for the uniqueness of the consistent chain. The first one is a transcription of a criterion due to Georgii for one-dimensional Gibbs measures, and the second one corresponds…
