摘要: 该文中,我们主要利用对Lie群G=SL(2,R)上球型函数的一些性质的讨论,给出了G上Fourier变换的一个重要的性质.即对每个γ∈Ǧ*,存在函数fCc(G),使得f(γ)≠0.

Abstract: In this paperi We will study some propcrties of spheri-cal functions on G=SL(2,R). By Virtue of these, we obtain that for each γ∈ Ǧ*, there exists a fCc(G)such that f(γ) ≠ 0. This result plays an important role in Fourier transform on SL(2,R).
