向下无跳马尔可夫链的拟平稳分布的存在性

Existence of quasi-stationary distributions for downward skip-free Markov chains

Kosuke Yamato

摘要:

研究了停于零的非负整数上无向下跳连续时间马尔可夫链的拟平稳分布的存在性。引入了这类过程的标度函数,并根据标度函数上的可积性条件对边界进行了分类,推广了Feller对生灭过程边界的分类.用尺度函数和边界的新分类刻画了拟平稳分布的存在性和拟平稳分布集。

英文摘要:

For downward skip-free continuous-time Markov chains on non-negative integers stopped at zero, existence of a quasi-stationary distribution is studied. The scale function for these processes is introduced and the boundary is classified by a certain integrability condition on the scale function, which gives an extension of Feller's classification of the boundary for birth-and-death processes. The existence and the set of quasi-stationary distributions are characterized by the scale function and the new classification of the boundary.
