                | This article investigates the convergence problem of Markov chains under the f norm. Using the basic coupling and the f norm equation, we obtain the su–cient conditions for the convergence of time homogeneous Markov chains in discrete-time general state spaces under the f norm are obtained, and the convergence of Markov chains under the total variation norm is extended. |
