Title: A Hecke module structure on the KK-theory of arithmetic groups When: Friday, 2 March 2018 at 1:10pm in Barr Smith South Polygon Lec theatre  Speaker: Bram Mesland (Unversität Bonn) Abstract: Let $G$ be a locally compact group, $\Gamma$ a discrete subgroup and $C_{G}(\Gamma)$ the commensurator of $\Gamma$ in $G$. The cohomology of $\Gamma$ is a […]

Fri 7 Aug 2015 12:10: Gromov’s method of convex integration and applications to minimal surfaces

Ingkarni Wardli B17 :: Finnur Larusson :: The University of Adelaide Abstract: We start by considering an applied problem. You are interested in buying a used car. The price is tempting, but the car has a curious defect, so it is not clear whether you can even take it for a test drive. This problem […]

Fri 31 Jul 2015 11:00: Quantising proper actions on Spin-c manifolds

Ingkarni Wardli Level 7 Room 7.15 :: Peter Hochs :: The University of Adelaide Abstract: For a proper action by a Lie group on a Spin-c manifold (both of which may be noncompact), we study an index of deformations of the Spin-c Dirac operator, acting on the space of spinors invariant under the group action. When […]
