Higher moments of intrinsic volumes of random beta-prime polytopes

Ferenc Fodor, Balázs Grünfelder, Péter Kevei

We consider beta-prime polytopes, i.e., the convex hulls of iid random points chosen according to beta-prime distributions in . After suitable scaling, beta-prime pol…

Path properties of Lévy driven mixed moving average processes

Danijel Grahovac, Péter Kevei, Orimar Sauri

We derive general sufficient conditions for the existence of càdlàg and continuous modifications of Lévy-driven mixed moving average processes. The conditions are explicit and easy…

Marcinkiewicz--Zygmund-type SLLN for mixed moving average processes

Danijel Grahovac, Péter Kevei, Dominik Mihalčić

The Marcinkiewicz--Zygmund theorem is a fundamental result in probability theory that establishes rates of convergence in the strong law of large numbers (SLLN). Although numerous…

Heavy-tailed critical Galton--Watson processes with immigration

Peter Kevei, Kata Kubatovics

Consider a critical Galton--Watson branching process with immigration, where the offspring distribution belongs to the domain of attraction of a -stable law with $α\in (0,…

Functional limit theorem for branching processes in nearly degenerate varying environment

Peter Kevei, Kata Kubatovics

We investigate branching processes in nearly degenerate varying environment, where the offspring distribution converges to the degenerate distribution at 1. Such processes die out…

Generalized Rényi statistics

Péter Kevei, László Viharos

In Rényi's representation for exponential order statistics, we replace the iid exponential sequence with any iid sequence, and call the resulting order statistic generalized Rényi…

Tail behavior and almost sure growth rate of supOU processes

Danijel Grahovac, Peter Kevei

In this paper we consider sample path growth of superpositions of Ornstein--Uhlenbeck type processes (supOU). SupOU processes are stationary infinitely divisible processes defined…

Almost sure growth of integrated supOU processes

Danijel Grahovac, Peter Kevei

Superpositions of Ornstein-Uhlenbeck processes allow a flexible dependence structure, including long range dependence for OU-type processes. Their complex asymptotics are governed…

Branching Processes with Immigration in a Random Environment -- the Grincevičius--Grey setup

Peter Kevei

We determine the tail asymptotics of the stationary distribution of a branching process with immigration in a random environment, when the immigration distribution dominates the of…

Branching model with state dependent offspring distribution for Chlamydia spread

Péter Kevei, Máté Szalai

Chlamydiae are bacteria with an interesting unusual developmental cycle. A single bacterium in its infectious form (elementary body, EB) enters the host cell, where it converts int…
