Absorbing **Markov Chains** † A state si of a **Markov** chain is called absorbing if it is impossible to leave it (i.e., pii = 1). † A **Markov** chain is absorbing if it has at least one absorbing state, and if from every state it is possible to go to an absorbing state (not necessarily in one step).
