Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：SOME PROPERTIES OF STATIONARY CONTINUOUS STATE BRANCHING PROCESSES

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...

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

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...

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
