摘 要: 本文解决了阿贝尔群上调和分析的如下经典问题:一组有序复数是G^(?)到D中的函敦f的付里叶谱的充分必要条件是甚么?这里D表示(?)(复数域),(?)(实数域)或G(有限阿贝尔群)。对子G=(?)_2的情形,已有的一些结论是本文主要定理的推论。 In this paper we solve the following classical problem of Harmonie Analysis on Abelian Groups. Which are the necessary and sufficient conditions that should be satisfied by an ordered set of complex numbers in order to be the Fourier-(Chrestenson)-Spectrum of a function, f: Gnf33D where D may denote , or G? We obtain as corollaries to the main theorems some known results for G = 2
