Let μ be a K-invariant compactly supported distribution on a noncompact Riemannian symmetric space X= G/K. If the spherical Fourier transform μ˜(λ) is slowly decreasing, it is known that the right convolution operator c μ: f↦ f⁎ μ maps E (X) onto E (X). In this paper, we prove the converse of this result. We also prove that c μ has a fundamental solution if and only if μ˜(λ) is slowly decreasing.
