On variation functions of lacunary series
Matyas Barczy, Peter Kern
We study variation functions of some lacunary series along the sequence of -adic partitions, where is an integer. By such a lacunary series, we mean that in the definition…
Expected loss of quasi-arithmetic means of exchangeable random variables
Matyas Barczy, Zsolt Páles
The purpose of this paper is to establish certain relationships between the theories of means (aggregation functions) and loss functions. Namely, we derive sufficient conditions un…
Distributional properties of first jump times of CBI processes with jump sizes in given Borel sets
Matyas Barczy, Sandra Palau, Yao Xue
We derive an expression for the joint distribution function of the first jump times of a continuous state and continuous time branching process with immigration (CBI process) with…
Asymptotic behavior of some strongly critical decomposable 3-type Galton--Watson processes with immigration
Matyas Barczy, Dániel Bezdány
We study the asymptotic behavior of a critical decomposable 3-type Galton-Watson process with immigration when its offspring mean matrix is triangular with diagonal entries 1. It i…
Distributional properties of jumps of multi-type CBI processes
Matyas Barczy, Sandra Palau
We study the distributional properties of jumps of multi-type continuous state and continuous time branching processes with immigration (multi-type CBI processes). We derive an exp…
Diffusion approximation of critical controlled multi-type branching processes
Matyas Barczy, Miguel González, Pedro Martín-Chávez +1
Branching processes form an important family of stochastic processes that have been successfully applied in many fields. In this paper, we focus our attention on controlled multi-t…
