AG Diskrete Mathematik und Mathematische Informatik
Winter Term 2007 / 2008

Prof. Dr. C.-P. Schnorr, Prof. Dr. T. Theobald
Dr. H. Bosse, R. Hartung, C. Riener, A. Scemama, R. Steffens

"AG Diskrete Mathematik und Mathematische Informatik" is meant as a place to communicate on research areas, which are related to discrete mathematics, cryptography, discrete geometry, theory of lattices, disrete and number-theoretic algorithms, and/or theoretical computer science. Anyone interested in these topics is kindly invited to attend.

Our first meeting will be on May, 11th. Talks will take place at Raum 612, Robert-Mayer-Straße 10, on Fridays at 14:15. map
