Explosion, implosion, and moments of passage times for continuous-time
Markov chains: a semimartingale approach
   [PDF]

Mikhail Menshikov, Dimitri Petritis
We establish general theorems quantifying the notion of recurrence ---
through an estimation of the moments of passage times --- for irreducible
continuous-time Markov chains on countably infinite state spaces. Sharp
conditions of occurrence of the phenomenon of explosion are also obtained. A
new phenomenon of implosion is introduced and sharp conditions for its
occurrence are proven. The general results are illustrated by treating models
having a difficult behaviour even in discrete time.
