Geometric branching reproduction Markov processes

open access: yesModern Stochastics: Theory and Applications, 2020
We present a model of a continuous-time Markov branching process with the infinitesimal generating function defined by the geometric probability distribution.

Three classifications on branching processes and their behavior for finding the solution of nonlinear integral equations

open access: yesMathematical Modelling and Analysis, 2010
In this paper, we consider the Monte Carlo method for finding the solution of nonlinear integral equations at a fixed point xo‐ In this method, simulated Galton‐Watson branching process is employed for solving the proposed integral equation.

A full lifespan model of vertebrate lens growth [PDF]

open access: yesRoyal Society Open Science, 2017
The mathematical determinants of vertebrate organ growth have yet to be elucidated fully. Here, we utilized empirical measurements and a dynamic branching process-based model to examine the growth of a simple organ system, the mouse lens, from E14.5 ...

Limiting Behaviors of Stochastic Spread Models Using Branching Processes

open access: yesAxioms, 2023
In this paper, we introduce a spread model using multi-type branching processes to investigate the evolution of the population during a pandemic in which individuals are classified into different types.

Branching Processes - A General Concept

open access: yesLatin American Journal of Probability and Mathematical Statistics, 2021
The paper has four goals. First, we want to generalize the classical concept of the branching property so that it becomes applicable for historical and genealogical processes (using the coding of genealogies by ($V$-marked) ultrametric measure spaces leading to state spaces $\mathbb{U}$ resp. $\mathbb{U}^V$).

Strong convergence of an epidemic model with mixing groups

open access: yes, 2023
We consider an SIR (susceptible → infective → recovered) epidemic in a closed population of size n, in which infection spreads via mixing events, comprising individuals chosen uniformly at random from the population, which occur at the points of a ...

Viral Marketing Branching Processes

open access: yesSSRN Electronic Journal, 2022
We consider the inherent timeline structure of the appearance of content in online social networks (OSNs) while studying content propagation. We model the propagation of a post/content of interest by an appropriate multi-type branching process. The branching process allows one to predict the emergence of global macro properties (e.g., the spread of a ...

Simply generated trees, conditioned Galton―Watson trees, random allocations and condensation: Extended abstract [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2012
We give a unified treatment of the limit, as the size tends to infinity, of random simply generated trees, including both the well-known result in the standard case of critical Galton-Watson trees and similar but less well-known results in the other ...

Estimating the risk of re-emergence after stopping polio vaccination

open access: yesFrontiers in Microbiology, 2012
Live vaccination against polio has effectively prevented outbreaks in most developed countries for more than 40 years, and there remain only a few countries where outbreaks of poliomyelitis by the wild strain still threaten the community.
