      Research Focus:
      Group Theory is one of the most fundamental domains of contemporary Mathematics. It is concerned with the study of 'groups', which are abstract representations of symmetries of mathematical objects. Group Theory plays a role in every branch of Pure and Applied Mathematics, and supplies powerful theoretical tools for solving problems in Physics, Chemistry, Information Science, and Engineering.

      The Geometric and Analytic Group Theory Research Team (GAGT Team) is at the forefront of the modern approach to the study of groups through analytic and geometric methods. These new methods have been extremely fruitful, and have led to the solution of several long-standing unsolved questions and opened new perspectives for further research. Analytic and Geometric Group Theory finds inspiration in methods from Analysis, Geometry, Combinatorics, Probability, Computer Networks, Crystallography, Quantum Mechanics, Relativity, and beyond. These methods are synthesized in an abstract framework to reveal the structure of groups. Conversely, the insights we gain by studying groups find application in these other domains. Analytic and Geometric Group Theory has become one of the main streams of Group Theory research, and is represented in major research centers worldwide. The GAGT Team, which started in Vienna in 2010, is the first research team in this field in Austria. Our current research interests include geometric, analytic, combinatorial, and computational aspects of group theory, low-dimensional topology, unitary representations and invariant measures, metric geometry, cryptography, complexity theory and randomization.

    • Univ.-Prof. Dr. Hans Georg Feichtinger

      Research Focus:
      I am working in Fourier Analysis and Function Spaces, specifically Gabor Analysis and Time-Frequency Analysis. In the past I have established the work-group NuHAG (with currently the members K. Gröchenig, M.Ehler, M.Dörfler, M Charina, J.L.Romero, P.Grohs), together with Prof. Gröchenig.
      We have published books in this area (1998,2001,2003), others in preparation.
      I have overall supervised ca. 8 Marie Curie Fellowships in the past, most of them pursuing now a good academic carreer: Massimo Fornasier (TU Muenich), Holger Rauhut (RWTH Aachen), Franz Luef (NTU Trondheim), S. Heineken (Buenos Aires), W.Czaja (College Park, MD, USA),... "
