Query: On the Titchmarsh convolution theorem for distributions on the circle   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.
