I am Professor at the Lehrstuhl D für Mathematik of the RWTH Aachen. My current research interests are integral representations of finite groups, lattices, spherical designs and modular forms, and their analogues in coding theory. You will find a brief CV (in german) if you click here. Upcoming conference Arithmetic of group rings and related structures at the RWTH Aachen university supported by the DFG SPP Representation theory. Lectures.. students. For a list of publications click here. Some talks. Diploma and PhD-Theses. Together with Neil J. A. Sloane we are building a database of interesting lattices New: The classification of perfect forms in dimension 8 is complete (Frank Vallentin, Achill Schürmann, Matthieu Dutour) Geometry of Lattices and Algorithms There are 10916 perfect lattices of dimension 8, only 2408 of them are extreme (local maxima of the density function). In the paper On Siegel modular forms of weight 12 ( ps-file) with B. Venkov, we calculate the action of some Hecke operators on the space generated by the 24 Niemeier lattices. You get the Hecke operators and the eigenforms in maple format if you click here. The structure constants for the multiplication of the eigenforms are in the big maple-file multiplication. The absolutely irreducible maximal finite subgroups of GL(n,D) for definite quaternion algebras D of dimension less than 40/n over the rationals are classified in my paper Finite quaternionic matrix groups. ( ps-file of a preprint) You find invariant Hermitian lattices for the about 300 primitive groups in 93 magma-readable files if you click here. links Fachgruppe Mathematik der RWTH Lehrstuhl B für Mathematik der RWTH Aachen Catalogue of lattices MAGMA ATLAS The prime page The number theory web Forum für Doktorandinnen der RWTH Gleichstellungsbeauftragte der RWTH Groups, Representations and Cohomology Preprint Archive LANL Preprint Archive Biographies of women mathematicians Archiv der Mathematik Mathematik Online GOOGLE Diese Seite ist auch auf Deutsch erhältlich.
