开马氏过程动力学涨落的大偏差及其在树上随机级联中的应用

Large Deviations for dynamical fluctuations of Open Markov processes, with application to random cascades on trees

Cecile Monthus

摘要:

本文讨论了C。Maes,K. Netocny和B. Wynants [Markov Proc. Rel.领域的14,445(2008)]的情况下,$N$独立马尔可夫跳过程的情况下,被扩展到开放的马尔可夫过程与水库的情况下:显式公式给出的经验占用数和经验流量的联合概率,离散时间动态和连续时间跳跃动态,可能与时间相关的动态规则和/或时间相关的驱动水库。这种一般的形式主义,然后应用到随机级联的树木,其中粒子被注入在根部通过一个“源hierarchy”,而粒子被删除在树叶的最后一代的树通过“汇hierarchy”。

英文摘要:

The large deviations at 'Level 2.5 in time' for time-dependent ensemble-empirical-observables, introduced by C. Maes, K. Netocny and B. Wynants [Markov Proc. Rel. Fields. 14, 445 (2008)] for the case of $N$ independent Markov jump processes, are extended to the case of open Markov processes with reservoirs : explicit formulas are given for the joint probability of empirical occupation numbers and empirical flows, both for discrete-time dynamics and for continuous-time jump dynamics, with possibly time-dependent dynamical rules and/or time-dependent driving of the reservoirs. This general formalism is then applied to random cascades on trees, where particles are injected at the root via a 'source reservoir', while the particles are removed at the leaves of the last generation of the tree via 'sink reservoirs'.
