ABSTRACT. We study the “Fourier symmetry ” of measures and distributions on the circle, in relation with the size of their supports. The main results of this paper are: (i) A one-side extension of Frostman’s theorem, which connects the rate of decay of Fourier transform of a distribution with the Hausdorff dimen-sion of the support; (ii) A construction of compacts of “critical ” size, which support distribu-tions (even pseudo-functions) with anti-analytic part belonging to l 2. We also give examples of non-symmetry which may occur for measures with “small ” support. A number of open questions are stated. RÉSUMÉ. On étudie la “symétrie de Fourier ” des mesures et des distributions sur le cercle en rapport avec la dimension de leurs supports....
