The Hausdorff Center for Mathematics (HCM) is a research institute in Bonn, founded by the four mathematical institutes of the Rheinische Friedrich-Wilhelms-Universität Bonn (Mathematical Institute, Institute for Applied Mathematics, Institute for Numerical Simulation, Research Institute for Discrete Mathematics), the Max Planck Institute for Mathematics (MPI) and the Institute for Social and Economic Sciences. It was established in 2006 as one of the seventeen national Clusters of Excellence that were part of the German government's Excellence Initiative. The centre was officially opened with a colloquium on 19 and 20 January, 2007. In 2012 a second funding period was granted.
