不可逆马尔可夫链的电网络

Electric network for non-reversible Markov chains

Márton Balázs, Áron Folly

摘要:

我们给出了不可逆马尔可夫链和电网络之间的类比,很大程度上类似于角谷以及后来的凯梅尼-斯内尔-纳普和凯利的经典可逆结果。电压倍增器--一种新的电子元件--使不可逆性成为可能。我们证明了吸收概率,逃逸概率,预期的跳跃数的边缘和通勤时间可以计算从电性质的网络在经典的情况下。中心量仍然是有效电阻,尽管单个部件不能被简单的电阻器所取代,但我们的网络中确实存在有效电阻。我们重写最近的不可逆的结果Gaudillière-Landim的Dirichlet和Thomson原则到电气语言。我们还提供了一些工具,可以帮助减少和解决网络。然而,我们的网络的微妙之处在于,经典的瑞利单调性丢失了。

英文摘要:

We give an analogy between non-reversible Markov chains and electric networks much in the flavour of the classical reversible results originating from Kakutani, and later Kemény-Snell-Knapp and Kelly. Non-reversibility is made possible by a voltage multiplier -- a new electronic component. We prove that absorption probabilities, escape probabilities, expected number of jumps over edges and commute times can be computed from electrical properties of the network as in the classical case. The central quantity is still the effective resistance, which we do have in our networks despite the fact that individual parts cannot be replaced by a simple resistor. We rewrite a recent non-reversible result of Gaudillière-Landim about the Dirichlet and Thomson principles into the electrical language. We also give a few tools that can help in reducing and solving the network. The subtlety of our network is, however, that the classical Rayleigh monotonicity is lost.
