WebA Schwartz function is clearly integrable, so we can take its Fourier transform. Lemma 4. The Fourier transform preserves the space of Schwartz functions. Moreover: (a) ˆˆ f = f(−t). (b) f∗g(s)=f(s) ∗ g(s) where f ∗ g(t)= ∞ −∞ f(x)g(t − x)dx is the convolution of f and g. (c) f(λt)(s)=1 λ f s λ ... WebJacobi functions and the spherical Fourier transformation reduces to the Jacobi transformation. Bloom and Xu [12] introduced spaces of Schwartz type (see Section 2 fordefinitions) on Ch´ebli-Trim`eche hypergroups. Theyinvestigatedthe generalized Fourier transformation on those spaces. Also they started the study of the #-convolution on the ...
