我们研究了一列具有非齐次移民的Galton--Watson过程在子代分布均值极限小于$1$或等于$1$时的渐近行为。在移民分布的期望值和子代分布的方差满足增长条件,并假设适当缩放的移民过程弱收敛于一个具有càdlàg或连续样本轨道的非负随机过程$\mathcal Y$的条件下,我们建立了所讨论的具有非齐次移民的Galton--Watson过程序列的泛函极限定理。极限随机过程可以表示为$\mathcal Y$的常数倍或积分泛函。
英文摘要
We study the asymptotic behavior of a sequence of Galton--Watson processes with inhomogeneous immigration when the limit of the means of the offspring distributions is less than $1$ or equal to $1$. Under growth conditions on the expected values of the immigration distributions and the variances of the offspring distributions, and assuming the weak convergence of properly scaled immigration processes towards a non-negative stochastic process $\mathcal Y$ with càdlàg or continuous sample paths, we establish functional limit theorems for the sequence of Galton--Watson processes with inhomogeneous immigration in question. The limit stochastic processes can be represented as a constant multiple or an integral functional of $\mathcal Y$.
