Tel Aviv University Hello everyone, The next colloquium talk will be held on Monday, 12/3/2012, 12:15, Schreiber 006, Tel Aviv University. The speaker is Andreas Bernig (Goethe-Universit\"at, Frankfurt) and the title of his talk is Algebraic integral geometry The abstract is given below. Tea and coffee at 12:00, same room. Hope to see you there. For information about future colloqiua, see <http://www.math.tau.ac.il/~klartagb/colloq_2011.html> You are all welcome to suggest colloquium speakers for this semester. Yours, Bo'az ------------- Abstract: We give a survey on a recent algebraic approach to kinematic formulas. The two main notions are that of "valuation" and of "curvature measure". It turns out that the space of valuations is an algebra and the space of curvature measures is a module over this algebra. On isotropic spaces, these algebraic structures are closely related to kinematic formulas. The kinematic formulas on complex space forms have been worked out explicitly (joint work with Joseph Fu and Gil Solanes). --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: <klartagb@post.tau.ac.il>
