Let ( Ω, F, P) be a probability space and X t = W t P a Brownian motion, i.e. a stochastic process with i.i.d. increments X t − X s ∼ N ( 0, t − s) and continuous sample paths P -a.s. and with X 0 = 0.

WebbBrownian motion with drift . So far we considered a Brownian motion which is characterized by zero mean and some variance parameter σ. 2. The standard Brownian motion is the special case σ = 1.
