<t>Hi, being a newbie at this forum, could I kindly ask all of you for some help? I have the following proofs to make:-Suppose Wt and Zt be two independent Brownian Motions. Show that Xt = [Wt + Zt]/sqrt(2) is also a Brownian motion.- For any real number Theta, let Zt = exp[theta*Wt- (theta^2*t)/2]....
