About

Stochastic processes (with either discrete or continuous time dependence) on a discrete (finite or countably infinite) state space in which the distribution of the next state depends only on the current state. For Markov processes on continuous state spaces please use (markov-process) instead.

A Markov chain is a stochastic process on a discrete (finite or countably infinite) space in which the distribution of the next state depends only on the current state. These objects show up in probability and computer science both in discrete-time and continuous-time models. For Markov processes on continuous spaces please use .
