Webwhere the latter is the ﬁnite-dimensional distribution of standard Brownian motion. See [Dur10]. The only problem with this approach is that the event C= f!: !(t) is continuous in tg; is not in F 0. See Exercise 8.1.1 in [Dur10]. Instead, we proceed as follows. There are several constructions of Brownian motion. Web0 is called the initial distribution of the Brownian motion B. If PfB 0 = xg= 1 for a point x 2R1, we say that the Brownian motion B starts from x. It is clear that if B is a Brownian motion starting from 0, then B + x = fBt + x, t 0gis a Brownian motion starting from x.

Weblength vector process then converges to a multi-dimensional reﬂecting Brownian motion (RBM) in heavy traﬃc (i.e. as the normalization factor tends to inﬁnity). This class of RBMs was ﬁrst introduced in Harrison and Reiman (1981). The stationary distribution of the RBM was shown to exist in Harrison and Williams (1987), and they proved that Webunderlying Brownian motion and could drop in value causing you to lose money; there is risk involved here. 1.1 Lognormal distributions If Y ∼ N(µ,σ2), then X = eY is a non-negative r.v. having the lognormal distribution; called so because its natural logarithm Y = ln(X) yields a normal r.v. X has density f(x) = (1 xσ √ 2π e −(ln(x)−µ)2 alasserWebBrownian motion is one of the most important stochastic processes in continuous time and with continuous state space. Within the realm of stochastic processes, Brownian motion is at the intersection of Gaussian processes, martingales, Markov processes, diffusions and random fractals, and it has influenced the study of these topics.
