Abstract

Let equation image be an open interval and let equation image and equation image. We characterize the surjectivity of the convolution operator Tμ: A(IG) → A(I) by means of a new estimate from below for the Fourier transform equation image valid on conical subsets of equation image. We also characterize when Tμ admits a continuous linear right inverse.
