Random walks with stochastic resetting in complex networks: a discrete time approach
Thomas M. Michelitsch, Giuseppe D'Onofrio, Federico Polito +1
We consider a discrete-time Markovian random walk with resets on a connected undirected network. The resets, in which the walker is relocated to randomly chosen nodes, are governed…
On count data models based on Bernstein functions or their inverses
G. D'Onofrio, F. Polito, Z. Tomovski
We present a class of positive discrete random variables extending the Conway--Maxwell-Poisson distribution. This class emerges in a natural way from an application in queueing the…
On discrete-time arrival processes and related random motions
Giuseppe D'Onofrio, Thomas M. Michelitsch, Federico Polito +1
We consider three kinds of discrete-time arrival processes: transient, intermediate and recurrent, characterized by a finite, possibly finite and infinite number of events, respect…
Orthogonal gamma-based expansion for the CIR's first passage time distribution
Elvira Di Nardo, Giuseppe D'Onofrio, Tommaso Martini
In this paper we analyze a method for approximating the first-passage time density and the corresponding distribution function for a CIR process. This approximation is obtained by…
