WebThe most important stochastic process is the Brownian motion or Wiener process. It was first discussed by Louis Bachelier (1900), who was interested in modeling fluctuations in … WebProblem 0. Read [Klebaner], Chapter4 and Brownian Motion Notes (by FEB 7th) Problem 1 (Klebaner, Exercise 3.4). Let fB tg t 0 be a standard Brownian Motion. Show that, fX tg 2[0;T], deﬁned as below is a Brownian Motion. a) X t = B t, We check that the deﬁning properties of Brownian motion hold. It is clear that B 0 = 0 a.s., and that WebThe idea is to use Fubini's theorem to interchange expectations with respect to the Brownian path with the integral.
