可数型线性分式分支过程

Linear-fractional branching processes with countably many types

Serik Sagitov

摘要:

本文利用轮廓过程、Spinal表示、可数矩阵的Perron-Frobenius定理、更新理论等分析工具研究了具有线性分式再生律的多型Bienaymé-Galton-Watson过程。对于这类具有可数多个类型的分支过程,我们给出了关于类型空间的$R$ -正常返性的一个透明判据。这个准则呼吁马尔萨斯参数和平均生育年龄的相关线性分数Crump-Mode-Jagers过程。

英文摘要:

We study multi-type Bienaymé-Galton-Watson processes with linear-fractional reproduction laws using various analytical tools like contour process, spinal representation, Perron-Frobenius theorem for countable matrices, renewal theory. For this special class of branching processes with countably many types we present a transparent criterion for $R$-positive recurrence with respect to the type space. This criterion appeals to the Malthusian parameter and the mean age at childbearing of the associated linear-fractional Crump-Mode-Jagers process.
