ABSTRACT
We obtain martingale characterizations for the generalized space fractional Poisson process (GSFPP) and for counting processes with Bernštein intertimes. These serve as extensions of the Watanabe's characterization for the classical homogenous Poisson process. The corresponding assertion for the space fractional Poisson process (SFPP) is obtained as a particular case of our results.
