[cmath] Bimonthly Canadian Noncommutative Geometry workshop, February

[Dan Kucerovsky]

This bimonthly workshop aims to cover new developments in Noncommutative 
Geometry, and each workshop features a keynote address by one of the top 
people in the field. The general theme for the first year is index theory. 
The second lecture will be given by Nigel Higson, 10:30am, on Saturday, 
February 2, 2008, at the Fields Institute in Toronto, Canada. Please 
forward this announcement to any graduate students or colleagues who might 
be interested.

The third lecture, by John Phillips, is tentatively scheduled for April 5, 
2008, at the Fields Institute.

The title and abstract for the forthcoming meeting are:

Title: K-Homology, Assembly and Rigidity Theorems for Relative Eta-Invariants

I shall describe a connection between K-homology theory and relative eta 
invariants, specifically a connection between the analytic surgery exact 
sequence, which is a long exact sequence into which Kasparov's assembly 
map fits, and rigidity theorems for relative eta invariants, such as for 
example the rationality of relative eta invariants on positive scalar 
curvature spin manifolds. A key part of the connection is the construction 
of a "relative trace map" on the fiber of the assembly map. The 
construction may be carried out either analytically or geometrically; I 
shall attempt to describe both approaches. This is joint work with John 
Roe.

Support for graduate students is available, please enquire, ncgworkshop at unb.ca.
