Weihnachtskolloquium
Vortragender: Prof. Dr. Konrad Polthier (FU Berlin)
"Vibrations of Geometric Shapes"
Beginn: 16:15
Ort: Raum 1.04, VSP 1
Abstract:
Vibrations of musical strings are well understood by Fourier analysis while the vibrations of geometric shapes exhibit surprising properties triggered by careful choices of differential geometric energies. We will review solved problems and introduce novel approaches with applications in biology, computer graphics and crystallography, and in topology.
Bio:
Konrad Polthier is full professor of mathematics at Freie Universität Berlin since 2005. He received his PhD from University of Bonn in 1994, and headed research groups a Technische Universität Berlin and Zuse Institute Berlin.
Since 2012 he is chair of the Berlin Mathematical Society, since 2014 EiC of Elsevier journal Computer Aided Geometric Design and since 2016 founder and chair of the conference series International Geometry Summit. His research focuses on discrete differential geometry, applied geometry, geometry processing and mathematical visualization. His results have been applied in industry, computer graphics, computer aided design and architecture.
Dr. Polthier has written and co-edited books on mathematical visualization and co-produced mathematical video films. His video MESH – A Journey Through Discrete Geometry (www.mesh-film.de ), joint with Beau Janzen, has received several international awards. His book „Bilder der Mathematik“ (www.bilder-der-mathematik.de ), joint with Georg Glaeser, was published in several issues in German and other languages by Springer.
