Papers from the RTN Workshop on the Quantum Structure of Spacetime and the Geometric Nature of Fundamental Interactions, Copenhagen, 15-20 September 2003

Abstract

The fourth annual conference of the European Research and Training Network on the Quantum Structure of Spacetime and the Geometric Nature of Fundamental Interactions was held in Copenhagen on 15-20 September 2003. As in previous conferences, each day started with an extended introductory lecture on a current topic relevant to the research of the Network. We would like to thank V Balasubramanian, G Dall'Agata, D Lüst, S Minwalla and R Russo for their effort in providing extensive lecture notes, which are included in these proceedings. In this way their lectures, which were very much appreciated by the participants of the conference, will become available to a wider audience. We thank also D Zanon for her lecture 'Non-perturbative results from perturbative field theory'. The shorter contributions are based on talks which represented research carried out within the Network. We also invited a number of outside speakers whose work was relevant to the topics covered by the conference. Their contributions are also included.This workshop took place in the context of the European Community Research and Training Networks' activities. Financial support came from the Niels Bohr Fund, NORDITA and the RTN. Much of the practical work was done by the conference secretariesH Christensen, U Holm, H Kiilerich, A Lumholdt and A Rey, to whom we are grateful. We also acknowledge important assistance from computer managers B Nilsson and P Urkedal. Last, but not least, we would like to thank Andrew Wray from Institute of Physics Publishing for his editorial help.
