Announcement and Application
Unfortunately, application deadline was already Dec. 15. Too bad. If anyone knows anything about this, please let me know.
Topic:
In the past two decades mathematicians started to investigate the geometric properties of manifolds by looking at their ambient loop spaces. The stimulation came from particle physists who analyzed these infinite dimensional objects heuristically. The results are very mystifying since they connect physics and differential topology with the theory of elliptic curves and modular forms.
An explanation is expected to come from a new cohomology theory which should be regarded as a higher version of topological K-theory. Such a theory can be obtained by methods of algebraic topology but its relation to loop spaces and field theories is still unclear.
Graeme Segal and Dan Quillen gave a first description of the elements in this new theory in terms of field theories. Later their approach was modified and improved by Stefan Stolz and Peter Teichner. The seminar gives an overview of their work while mainly focusing on the relationship between 1-dimensional euclidean field theories and classical K-theory which is now understood.
Re: Winter School on Elliptic Objects
Hallo, Urs!
In case you don’t already know, I remembered that John (Baez) has written something on Elliptic Cohomology in his twf’s. I went back and read it again (when it was originally written I was an undergrad and had no chance to gasp the meaning of anything - I don’t claim things have gotten much better since).
you can find a generel introduction to general homology theory in week 149 and 150, a little bit concerning elliptic cohomology in week 153 and more in 197.
Enjoy!
