Asymptotics of the occupation measure defined on a nonnegative matrix of two-dimensional quasi-birth-and-death type

Toshihisa Ozawa

We consider a nonnegative matrix having the same block structure as that of the transition probability matrix of a two-dimensional quasi-birth-and-death process (2d-QBD process for…
