摘要:For most applications, the Plancherel formula undertakes the routine role of an effectual tool used to obtain quantitative results, but certainly, that is unsuited to non-square-integrable functions. Norbert Wiener ever proved a quantitative formula (Wiener-Plancherel formula) for functions f which are only averagely bounded, that is an equality of limits relating some kind of quadratic behavior of the associated functions. In a recent work, we generalize Wiener’s work and prove a Wiener-Plancherel-type formula for functions of polynomial growth at infinity.
