Let [math]\mat{P}[/math] be the transition matrix of a regular
Markov chain. Assume that there are [math]r[/math] states and let [math]N(r)[/math] be the smallest integer [math]n[/math] such that [math]\mat{P}[/math] is regular if and only if [math]\mat {P}^{N(r)}[/math] has no zero entries. Find a finite upper bound for [math]N(r)[/math]. See if you can determine [math]N(3)[/math] exactly.
