Does the definition of positive or null recurrence require aperiodicity?

$begingroup$


Do the notions of null or positive recurrence have to be defined with respect to irreducible, aperiodic chains or does irreducibility suffice?

    Sorry but after your rapid succession of basic questions on the subject, one needs to know: are you following a textbook? If not, why?

    @Did I am following a textbook and that is where this question came from. In Lawler's Stochastic Processes, Chapter 2 defines null and positive recurrence only for irreducible, aperiodic chains, which is why I wonder whether periodicity is needed here?

    @Did Ditto for the other two questions I posed; I was not able to find an answer to either on the book. If you could point me to a resource or post an answer, I would gladly accept it.

    The trouble is that you seem to stumble on very basic obstacles, well below the subject you are trying to tackle... hence my advice for a reference would be a mildly general and mildly complete textbook on probability theory (say, Durrett), to be worked on thoroughly before continuing the present string of essentially irrelevant questions.
