Hermann Schulz-Baldes
(Friedrich-Alexander-Universität Erlangen-Nürnberg)
will give a talk in lecture hall A027 on
The Spectral Localizer: A New Tool for Index Theory
Abstract: Index pairings resulting from pairings of K-groups with Fredholm modules are intrinsically objects of infinite dimensional analysis, but with the spectral localizer a new player has appeared on the scene and opens the doors for numerical K-theory. I will illustrate these ideas by means of an elementary example, namely Fritz Noether's index theorem for the winding number of a continuous and invertible complex function. (Joint work with Terry Loring).
Everyone is invited! Join us for coffee and tea in the common room (B448) half an hour before the talk.
