Web24 aug. 2012 · The first bound is rather easy to be obtained since the needed condition, equivalent to uniform ergodicity, is imposed on the transition matrix directly. The second bound, which holds for a general (possibly periodic) Markov chain, involves finding a drift function. This drift function is closely related with the mean first hitting times. WebIn probability theory, in particular in the study of stochastic processes, a stopping time (also Markov time, Markov moment, optional stopping time or optional time [1]) is a specific type of “random time”: a random variable whose value is interpreted as the time at which a given stochastic process exhibits a certain behavior of interest.

Web23 apr. 2024 · Definition. A standard Brownian motion is a random process X = {Xt: t ∈ [0, ∞)} with state space R that satisfies the following properties: X0 = 0 (with probability 1). X has stationary increments. That is, for s, t ∈ [0, ∞) with s < t, the distribution of Xt − Xs is the same as the distribution of Xt − s. X has independent increments.
