WebDEF 27.9 (Brownian motion: Definition II) The continuous-time stochastic pro-cess X= fX(t)g t 0 is a standard Brownian motion if Xhas almost surely con-tinuous paths and stationary independent increments such that X(s+t) X(s) is Gaussian with mean 0 and variance t. THM 27.10 (Existence) Standard Brownian motion B= fB(t)g t 0 exists. A Wiener process (also known as Brownian motion) is the integral of a white noise generalized Gaussian process. It is not stationary, but it has stationary increments. The Ornstein–Uhlenbeck process is a stationary Gaussian process. The Brownian bridge is (like the Ornstein–Uhlenbeck process) an example of a Gaussian process whose increments are not independent. iphone 2634 https://ticoniq.com
