WebbThe simple random walk is a simple but very useful model for lots of processes, like stock prices, sizes of populations, or positions of gas particles. (In many modern models, … WebbFor this paper, the random walks being considered are Markov chains. A Markov chain is any system that observes the Markov property, which means that the conditional probability of being in a future state, given all past states, is dependent only on the present state. In short, Section 2 formalizes the de nition of a simple random walk on the

Webb1 mars 2024 · Probability and analysis informal seminarRandom walks on groups are nice examples of Markov chains which arise quite naturally in many situations. Their key feature is that one can use the algebraic properties of the group to gain a fine understanding of the asymptotic behaviour.
