“Partial ensemble averages in geometric Brownian motion” submitted.

In this paper Ole Peters and Bill Klein clarify two important issues in geometric Brownian motion. They show analytically, using extreme-value theory, that the time-average growth rate for a finite ensemble is the same as Read more
