Brownian motion
From Encyclopedia of Mathematics
2020 Mathematics Subject Classification: Primary: 60J65 [MSN][ZBL]
The process of chaotic displacements of small particles suspended in a liquid or in a gas which is the result of collisions with the molecules of the medium. There exist several mathematical models of this motion [P]. The model of Brownian motion which is the most important one in the theory of random processes is the so-called Wiener process, and the concept of Brownian motion is in fact often identified with this model.
