WebI marked "staying" because Brownian motion continuous but non differentiating function, it does not stay but cross the points. There is no probability of a given point but there is a probability density of crossings the given point on interval [0,T). Which can be computed as integral of Brownian motion with dirac delta (if I am not wrong). Web1 Answer. We can write B ( u + v) + B ( u) = ( B ( u + v) − B ( u)) + 2 B ( u). But B ( u + v) − B ( u) is independent of B ( u) and should have the same distribution as B ( v). So E [ B ( …
