Markov chains: recurrent states

Dependencies:

  1. Markov chain

Let X=[X0,X1,] be a markov chain. Let Ri=t=1(Xt=i), i.e., Ri is the event that we'll enter state i at some time t1. Then state i is said to be recurrent iff Pr(RiX0=i)=1. Intuitively, this means state i is recurrent iff we will always come back to state i if we start from it.

Dependency for:

  1. Markov chains: positive recurrence
  2. Markov chains: recurrent state to acessible state (incomplete)
  3. Markov chains: recurrent iff infinite visits
  4. Markov chains: long run proportion is inverse of time to reenter (incomplete)
  5. Markov chains: recurrence is a class property
  6. Markov chains: finite sink is recurrent (incomplete)
  7. Markov chains: recurrent class is sink
  8. Markov chains: recurrent iff expected number of visits is infinite
