Brownian motion and Riemann zeta function
In mathematics, the Brownian motion and the Riemann zeta function are two central objects of study in mathematics originating from different fields - probability theory and analytic number theory - that have mathematical connections between them. The relationships between stochastic processes derived from the Brownian motion and the Riemann zeta function show in a sense intuitively the stochastic behaviour underlying the Riemann zeta function.
