Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：SOME PROPERTIES OF STATIONARY CONTINUOUS STATE BRANCHING PROCESSES
稳态 连续状态 分支过程 性质
2023/4/14
We consider the genealogical tree of a stationary continuous state branching process with immigration. For a sub-critical stable branching mechanism, we consider the genealogical tree of the extant po...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Multitype branching processes in random environments
随机环境 多类型 分支进程
2023/4/18
We consider a branching process with a random environment, in which the reproduction law of generation $n$ depends on the random environment at time n, unlike a constant distribution assumed in the cl...
Small Value Probabilities for Supercritical Branching Processes with Immigration
Supercritical Galton-Watson branching process small value probability immigration
2016/1/25
We consider a supercritical Galton-Watson branching process with immigration. It is well known that under suitable conditions on the offspring and immigration distributions, there is a finite,strictly...

In this paper we study the conditional limit theorems for critical continuous-state branching processes with branching mechanism ψ(λ) = λ 1+α L(1/λ)where α ∈ [0,1] and L is slowly varying at ∞. We pro...

We consider a supercritical Galton-Watson branching process with immigration. It is well known that under suitable conditions on the offspring and immigration distributions, there is a finite,strictly...
Asymptotic behavior of critical primitive multi-type branching processes with immigration

2012/5/24
Under natural assumptions a Feller type diffusion approximation is derived for critical multi-type branching processes with immigration when the offspring mean matrix is primitive (in other words, pos...
A Lamperti type representation of Continuous-State Branching Processes with Immigration
Levy processes Continuous branching processes with immigration time-change
2011/1/20
Guided by the relationship between the breadth- rst walk of a rooted tree and its sequence of generation sizes, we extend the Lamperti representation of continuous-state branching processes to allow i...
Smaller population size at the MRCA time for stationary branching processes
Branching process most recent common ancestor bottleneck genealogy
2010/11/30
We present an elementary model of random size varying population given by a stationary continuous state branching process. For this model we compute the joint distribution
of: the time to the most re...
General branching processes conditioned on extinction are still branching processes
supercritical Bienayme-Galton-Watson process branching process
2009/3/23
It is well known that a simple, supercritical Bienaymé-Galton-Watson process turns into a subcritical such process, if conditioned to die out. We prove that the corresponding holds true for general, m...
Inference for Partially Observed Multitype Branching Processes and Ecological Applications
Parametric inference Incomplete data Multitype branchingprocesses ecology
2010/3/18
Multitype branching processes with immigration in one type are
used to model the dynamics of stage-structured plant populations.
Parametric inference is first carried out when count data of all type...
