Manifolds, quadratic forms and bagels
Mathematisches Kolloquium

Referent: Prof. Dr. Andrew Ranicki, University of Edinburgh
Raum: S2 14/24

Zuvor findet um 16.45 Uhr die Teerunde im dritten Stock des Mathematikgebäudes, Schlossgartenstr. 7, statt.


The Poincare duality properties of manifolds give rise to quadratic structures in the homology,  and hence also to various numerical invariants such as the integer-valued signature. In the last 40 years index theory has led to the development of real-valued invariants, which have not yet been fully   internalized by topologists. The talk will outline some recent progress, including an application of the Maslov index to the art of slicing a bagel.
