论非负整数上作为随机游走的迁出与迁入之间的平衡

On the balance between Emigration and Immigration as Random Walks on the non-negative integers

Thierry Huillet

AI总结:

本文通过三个马尔可夫链种群模型,研究随机迁入与迁出之间的平衡如何决定种群稳定性,并揭示外部需求与衰老两种不同移除机制对稳定性条件的影响。

摘要:

生命处于剃刀边缘,这是由竞争性的出生与死亡随机力量所导致的结果。我们在三个马尔可夫链种群模型的背景下阐释这一格言,在这些模型中,促进增长的系统性随机迁入事件与引发稀疏化的随机迁出事件同时达到平衡。大规模移除的起源要么由外部需求决定,要么由衰老决定,从而导致不同的稳定性条件。

英文摘要:

Life is on the razor's edge as resulting from competitive birth and death random forces. We illustrate this aphorism in the context of three Markov chain population models where systematic random immigration events promoting growth are simultaneously balanced with random emigration ones provoking thinning. The origin of mass removals are either determined by external demands or by aging leading to different conditions of stability.
