报告主题：Covering and Uncovering Surfaces
报告人：Konrad Polthier 教授
Abstract: Multivalued functions and differential forms naturally lead to the concept of covering surfaces and more generally of covering manifolds. This talk will review, illustrate and discretize basic concepts of branched covering surfaces starting from complex analysis, surface theory up to their recent appearance in geometry processing algorithms. Applications will touch artistic surface modeling, geometry retargeting, surface and volume parameterization.
Konrad Polthier (Freie Universität Berlin):
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 before joining FU Berlin. His research focuses on discrete differential geometry, applied geometry, geometry processing and mathematical visualization. Results from him have been applied in industry such as computer graphics, computer aided design and architecture. Dr. Polthier has written and co-edited books on mathematical visualization and produced mathematical video films. His video “MESH – A Journey through Discrete Geometry” (www.mesh-film.de<http://www.mesh-film.de> joint with Beau Janzen, Los Angeles) has received international awards including "Best Animation" at the New York International Independent Film Festival. Polthier served as conference chair on international conferences including ACM/Eurographics Symposium on Geometry Processing and SIAM Geometric Design. His professional positions include chair of the Berlin Mathematical School, board member of the Matheon research center and chair of the Berlin Mathematical Society. Since May 2014 he serves as co-editor in chief of Computer Aided Geometric Design.
