Geometric Brownian motion Geometric Brownian motion A geometric Brownian motion (GBM) (also known as exponential Brownian motion) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion (also called a Wiener process) with drift. It is an important example of stochastic processes satisfying a stochastic differential equation (SDE); in particular, it is used in mathematical finance to model stock prices in the Black–Scholes model. A stochastic process "S" is said to follow a GBM if it satisfies the following stochastic differential equation (SDE): where formula_2 is a Wiener process or Brownian motion, and formula_3 ('the
Brownian Motion Ultimate proving that Brownian Motion could compete with the best teams in the country. It was also at this time that Brownian Motion re-constituted its "B" team, nicknamed Polyester Funkadelic or P-Funk. The success of 1998 continued as Brown lost only one other game on its way to its first National's berth ever in the Spring season. At Nationals, Brown went 3-3, losing to the eventual champions UC Santa Barbara and Stanford. However, Brown also beat the third ranked Carleton College 13-12. Brown left nationals as one of the top ranked college programs in the nation. These years also gave the
