Generalized fractional calculus and some models of generalized counting processes

Khrystyna Buchak, Lyudmyla Sakhno

In the paper we consider models of generalized counting processes time-changed by a general inverse subordinator, we characterize their distributions and present governing equation…

Properties of Poisson processes directed by compound Poisson-Gamma subordinators

Khrystyna Buchak, Lyudmyla Sakhno

In the paper we consider time-changed Poisson processes where the time is expressed by compound Poisson-Gamma subordinators G(N(t)) and derive the expressions for their hitting t…

Compositions of Poisson and Gamma processes

Khrystyna Buchak, Lyudmyla Sakhno

In the paper we study the models of time-changed Poisson and Skellam-type processes, where the role of time is played by compound Poisson-Gamma subordinators and their inverse (or…
