... A linear equation in one variable is an equation that can be written in the form ax = b where a and b are constants and a ≠ 0. A number is a solution of an equation if the statement is true when the number is substituted for the variable. Two equations are equivalent if they have the same solutions. ...

Itô diffusion
In mathematics — specifically, in stochastic analysis — an Itô diffusion is a solution to a specific type of stochastic differential equation. That equation is similar to the Langevin equation used in physics to describe the Brownian motion of a particle subjected to a potential in a viscous fluid. Itô diffusions are named after the Japanese mathematician Kiyosi Itô.
