University of Haifa The Department of Mathematics Faculty of Natural Sciences The Center for Mathematics & Scientific Computation invite you to a Distinguished Lecture Series to be given by Professor Peter Teichner (Max Planck Institute & University of California, Berkeley) on Manifolds in dimension four and higher (Previous lecture: Manifolds and modular forms) Second of three lectures · On Tuesday, April 30, 2013 at 16:30 PM Four-manifolds revisited We will present known results about 4-dimensional manifolds, with a focus on Whitney's trick. We will not require any background but a willingness to visualize 4-dimensional objects · On Wednesday, May 1, 2013 at 10:30 AM Whitney towers in the 4-ball The failure of the Whitney trick in dimension four can be measured via an intersection theory of Whitney towers. We will summarize several recent joint papers with Jim Conant and Rob Schneiderman. All lectures will take place in room 570 of Science & Education Building For further information call 04-8240699, 04-8249294. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: David Blanc <BLANC@MATH.HAIFA.AC.IL>
