Editing Gauss–Kuzmin–Wirsing operator (section)

In [[mathematics]], the '''Gauss–Kuzmin–Wirsing operator''' is the [[transfer operator]] of the Gauss map that takes a positive number to the fractional part of its reciprocal. (This is not the same as the [[Gauss map]] in [[differential geometry]].) It is named after [[Carl Gauss]], [[Rodion Kuzmin]], and [[Eduard Wirsing]]. It occurs in the study of [[continued fractions]]; it is also related to the [[Riemann zeta function]].
