## Renewal processes of Mittag-Leffler and Wright type.(English)Zbl 1126.60070

Authors’ abstract: After sketching the basic principles of renewal theory we discuss the classical Poisson process and offer two other processes, namely, the renewal process of Mittag-Leffler type and the renewal process of Wright type, so named because special functions of Mittag-Leffler and of Wright type appear in the definition of the relevant waiting times. We compare these three processes with each other, furthermore, consider corresponding renewal processes with reward and, numerically, their long-term behaviour.
