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.

Abstract:

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.
