Although the technical details will not be discussed, as the number of steps N becomes infinite, the Wiener process is obtained, more commonly called a standard Brownian motion, which will be denoted by B(t). Formally, the definition is given by: Definition: Wiener Process/Standard Brownian M...
fractional Brownian motionHaar functionspower variationSchauder functionsWiener processIn this chapter, a Wiener process is constructed on the interval [0, 1]. The sequences of Haar and Schauder functions on this interval are also considered. There exists a Wiener process with continuous trajectories....
