Branching Particle Systems and Compound Poisson Processes Related to Pólya-aeppli Distributions

چکیده
We establish numerous new refined local limit theorems for a class of compound Poisson processes with Pólya-Aeppli marginals, and for a particular family of the branching particle systems which undergo critical binary branching and can be approximated by the backshifted Feller diffusion. To this end, we also derive new results for the families of Pólya–Aeppli and Poisson–exponential distributions. We relate a few of them to properties of certain special functions some of which were previously unknown.

The Pólya - Aeppli distribution of order k
In this paper the Pólya Aeppli distribution of order k as a compound Poisson distribution is defined. The probability mass function and recursion formulas are given. We consider the interpretation of the distribution and a definition of the Pólya Aeppli process of order k.
متن کاملLocal Approximations for Branching Particle Systems
We derive different local approximations along with estimates of the remainders for the total mass processes of two branching particle systems. To this end, we investigate the corresponding classes of integer-valued variables. One of them is comprised of Pólya-Aeppli distributions, while members of the other class are the convolutions of a zero-modified geometric law. We obtain the closed-form ...
متن کاملThe Pólya-aeppli Process and Ruin Problems
The Pólya-Aeppli process as a generalization of the homogeneous Poisson process is defined. We consider the risk model in which the counting process is the Pólya-Aeppli process. It is called a Pólya-Aeppli risk model. The problem of finding the ruin probability and the Cramér-Lundberg approximation is studied. The Cramér condition and the Lundberg exponent are defined. Finally, the comparison b...
متن کاملNumerical solution and simulation of random differential equations with Wiener and compound Poisson Processes
Ordinary differential equations(ODEs) with stochastic processes in their vector field, have lots of applications in science and engineering. The main purpose of this article is to investigate the numerical methods for ODEs with Wiener and Compound Poisson processes in more than one dimension. Ordinary differential equations with Ito diffusion which is a solution of an Ito stochastic differentia...
متن کاملAssessing the Exceptionality of Coloured Motifs in Networks
Various methods have been recently employed to characterise the structure of biological networks. In particular, the concept of network motif and the related one of coloured motif have proven useful to model the notion of a functional/evolutionary building block. However, algorithms that enumerate all the motifs of a network may produce a very large output, and methods to decide which motifs sh...
