Query: Characterizations and Infinite Divisibility of Extended COM-Poisson
  Distribution   This article provides some characterizations of extended COM-Poisson
distribution: conditional distribution given the sum, functional operator
characterization (Stein identity). We also give some conditions such that the
extended COM-Poisson distribution is infinitely divisible, hence some subclass
of extended COM-Poisson distributions are discrete compound Poisson
distribution.
