DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/67/">In
 trinsic volumes on pseudo-Riemannian manifolds</a>\nby Andreas Bernig (Goe
 the University Frankfurt) as part of Online Seminar "Geometric Analysis"\n
 \n\nAbstract\nThe intrinsic volumes in Euclidean space can be defined via 
 Steiner's tube formula and were characterized by Hadwiger as the unique co
 ntinuous\, translation and rotation invariant valuations. By the Weyl prin
 ciple\, their extension to Riemannian manifolds behaves naturally under is
 ometric embeddings.\n\nIn a series of papers with Dmitry Faifman and Gil S
 olanes\, we developed a theory of intrinsic volumes in pseudo-Euclidean sp
 aces and on pseudo-Riemannian manifolds. Fundamental results like Hadwiger
 's theorem\, Weyl's principle and Crofton formulas on spheres have their n
 atural analogues in the pseudo-Riemannian setting.\n
