Riemann-Roch Theorem for Circle
Bundles
ABSTRACT:
To the data of a circle bundle
and a vector bundle on the total space thereof I will associate a
characteristic class taking values in the (degree three) cohomology of
the base and show how it arises as a fiberwise integral. Time
permitting I will discuss generalizations to higher relative dimensions.
