A time-continuous stochastic process devised by the American mathematician N. Wiener. In addition to being a mathematical model of Brownian motion, it is widely used in both pure and applied mathematics, including in the diffusion process in thermodynamics, noise theory in electronic engineering, and the Black-Scholes equation in financial engineering.
