During the conference eight open problems were posed by Magnus, Berg, van Doom, Everitt, Gilewicz, Koornwinder, Ronveaux and Siafarikas. An extra problem by Prudnikov reached us after the conference and is also added. Two of these problems were already solved by the end of the conference. Later Peherstorfer gave the solution of another problem and of a problem posed at the Erice meeting, which is also added. We look forward to see solutions of the other problems as well and hope they stimulate the interaction between various research groups.
