Non-homogeneous Random Walks: Lyapunov Function Methods for by Mikhail Menshikov,Serguei Popov,Andrew Wade

By Mikhail Menshikov,Serguei Popov,Andrew Wade

Stochastic platforms supply strong summary types for a number of very important real-life purposes: for instance, energy provide, site visitors circulate, information transmission. They (and the genuine structures they version) are frequently topic to part transitions, behaving in a single method whilst a parameter is lower than a undeniable serious price, then switching behaviour once that serious worth is reached. In a true process, we don't unavoidably have keep watch over over the entire parameter values, so you will need to know the way to discover serious issues and to appreciate procedure behaviour close to those issues. This publication is a latest presentation of the 'semimartingale' or 'Lyapunov functionality' strategy utilized to near-critical stochastic structures, exemplified via non-homogeneous random walks. purposes deal with near-critical stochastic structures and diversity throughout glossy chance thought from stochastic billiards types to interacting particle structures. Spatially non-homogeneous random walks are explored intensive, as they supply prototypical near-critical systems.
