可列非齐次马氏链的若干极限定理 总被引:15,自引:0,他引:15
非齐次马氏链的极限定理曾被不少作者研究过,在他们的工作中分别对马氏链作了相应的限制(参见[1]—[9])。本文的主要工作是给出对任意非齐次马氏链均成立的一类关于状态和状态序偶出现频率的极限定理。在证明中本文提出了一种与传统方法不同的方法——分割单位区间法,其要点是在Wiener概率空间给出马氏链的一种实现,并定义适当的单调函数,然后应用单调函数导数存在定理来证明有关极限几乎处处存在。 相似文献

Markov chain approximations of reversible jump processes are investigated. Tightness results and a central limit theorem are
established. Moreover, given the generator of a reversible jump process with state space ℝ
d
, the approximating Markov chains are constructed explicitly. As a byproduct we obtain a definition of the Sobolev space H
α/2(ℝ
d
), α∈(0,2), that is equivalent to the standard one.

It is our aim to improve the limit theory of supercritical Bienaymé—Galton—Watson processes with varying environment (cf. [3], [4]), and to simultaneously construct its continuous-time analogue. We give a necessary and sufficient condition for the existence of a non-degenerate limit with expectation norming and show that if the limit is non-degenerate, its expectation must be equal to 1. We continue with a result on the expectation of the limit in case of general norming and conditions for the continuity and strict monotonicity of the limiting distribution function. Finally, we reformulate the non-degeneracy condition. 相似文献

The literature about maximum of entropy for Markov processes deals mainly with discrete-time Markov chains. Very few papers dealing with continuous-time jump Markov processes exist and none dealing with semi-Markov processes. It is the aim of this paper to contribute to fill this lack. We recall the basics concerning entropy for Markov and semi-Markov processes and we study several problems to give an overview of the possible directions of use of maximum entropy in connection with these processes. Numeric illustrations are presented, in particular in application to reliability. 相似文献

本提出了新的非齐次马尔可夫链的遍历条件,并在此条件下,首次证明了非齐次马尔可夫链转移概率的Gesaro-极限定理。另外,本还给出了一个例子,用它表明本的条件确实比Doeblin条件要弱。 相似文献

We present a concise, yet self-contained module for teaching the notion of areaand the Fundamental Theorem of Calculus for different groups of students. Thismodule contains two different levels of rigour, depending on the class it usedfor. It also incorporates a technological component. 相似文献

In the paper, it is shown how, by using the minimal means and without introducing complex numbers, one can prove the fundamental theorem of algebra for real polynomials. The fundamental theorem for polynomials with complex coefficients is an immediate corollary of the theorem mentioned. 相似文献
