On the powers of maximal ideals in the measure algebra (Q277368)

The author of the paper under review, for a locally compact abelian group, considers the corresponding measure algebra and studies powers of maximal ideals in terms of the derivatives of the Fourier-Laplace transform of compactly supported measures. He shows that if the locally compact abelian group has sufficiently many real characters, then all derivatives of the Fourier-Laplace transform of a measure at some point of its spectrum completely characterize the measure.
