%0 Journal Article %T On the Titchmarsh convolution theorem for distributions on the circle %A Andrew Comech %A Alexander Komech %J Mathematics %D 2011 %I arXiv %X We prove a version of the Titchmarsh convolution theorem for distributions on the circle. We show that the "naive form" of the Titchmarsh theorem could be violated, but that such a violation is only possible for the convolution of distributions which both possess certain symmetry properties. %U http://arxiv.org/abs/1108.2463v5
