  • The Scientific Context
    Center for Quantum Geometry of Moduli Spaces Proposal for the Danish National Research Foundation The Scientific Context: The role of mathematics in our understanding of nature has been recognized for millennia. Its importance is especially poignant in modern theoretical physics as the cost of experiment escalates and the mathematical complexity of physical theories increases. Major challenge: Discover the mathematical mechanisms to define quantum field theory as a mathematical entity, to justify mathematically the recipes used by physicists, and to unify quantum theory with gravity. Classical and quantum mechanics rests on solid mathematical foundations, which were developed over the last two centuries. In contrast, quantum field theory, which plays a central role in modern theoretical physics, lacks a mathematical foundation. The mathematical difficulties involve averaging over infinite-dimensional spaces, which have defied rigorous interpretation and yet are effective in practice according to explicit recipes in physics. For example, the Standard Model of particle physics successfully predicts to a dozen decimals experimental results from high-energy colliders such as CERN or SLAC. Quantum field theory has enjoyed several important successes in the last two decades where a number of models were constructed despite the difficulties described above. In all these cases, the theory admits a large family of symmetries, and the problematic infinite-dimensional averages reduce to averages over smaller ensembles, called moduli spaces, which are in many cases finite-dimensional and permit mathematically rigorous calculations. Also, low-dimensional models unifying gravity with quantum theory have been developed successfully, and the key geometrical objects are again moduli spaces. Quantum geometry, so-named since the quantization arises from geometric methods designed to make a passage from classical geometry to quantum theory, plays the fundamental role in all these constructions.

  • New Trends in Teichmüller Theory and Mapping Class Groups
    Mathematisches Forschungsinstitut Oberwolfach Report No. 40/2018 DOI: 10.4171/OWR/2018/40 New Trends in Teichm¨uller Theory and Mapping Class Groups Organised by Ken’ichi Ohshika, Osaka Athanase Papadopoulos, Strasbourg Robert C. Penner, Bures-sur-Yvette Anna Wienhard, Heidelberg 2 September – 8 September 2018 Abstract. In this workshop, various topics in Teichm¨uller theory and map- ping class groups were discussed. Twenty-three talks dealing with classical topics and new directions in this field were given. A problem session was organised on Thursday, and we compiled in this report the problems posed there. Mathematics Subject Classification (2010): Primary: 32G15, 30F60, 30F20, 30F45; Secondary: 57N16, 30C62, 20G05, 53A35, 30F45, 14H45, 20F65 IMU Classification: 4 (Geometry); 5 (Topology). Introduction by the Organisers The workshop New Trends in Teichm¨uller Theory and Mapping Class Groups, organised by Ken’ichi Ohshika (Osaka), Athanase Papadopoulos (Strasbourg), Robert Penner (Bures-sur-Yvette) and Anna Wienhard (Heidelberg) was attended by 50 participants, including a number of young researchers, with broad geo- graphic representation from Europe, Asia and the USA. During the five days of the workshop, 23 talks were given, and on Thursday evening, a problem session was organised. Teichm¨uller theory originates in the work of Teichm¨uller on quasi-conformal maps in the 1930s, and the study of mapping class groups was started by Dehn and Nielsen in the 1920s. The subjects are closely interrelated, since the mapping class group is the

  • Moduli Spaces and Macromolecules
    BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY Volume 53, Number 2, April 2016, Pages 217–268 http://dx.doi.org/10.1090/bull/1524 Article electronically published on February 3, 2016 MODULI SPACES AND MACROMOLECULES R. C. PENNER Abstract. Techniques from moduli spaces are applied to biological macro- molecules. The first main result provides new a priori constraints on protein geometry discovered empirically and confirmed computationally. The second main result identifies up to homotopy the natural moduli space of several in- teracting RNA molecules with the Riemann moduli space of a surface with several boundary components in each fixed genus. Applications to RNA fold- ing prediction are discussed. The mathematical and biological frameworks are surveyed and presented from first principles. Contents Introduction 218 1.
