In mathematics, the stationary phase approximation is a basic principle of asymptotic analysis, applying to functions given by integration against a rapidly-varying complex exponential.
This method originates from the 19th century, and is due to George Gabriel Stokes and Lord Kelvin.[1] It is closely related to Laplace's method and the method of steepest descent, but Laplace's contribution precedes the others.
