notes,
THE WITTEN GENUS, AFTER KEVIN COSTELLO
(2010)
Abstract
These are notes from the Witten Genus Seminar that took place at the
Max Planck Institute in Bonn, Fall 2010. Any errors in what follows
are mine.
In a series of two papers Cos10a, Cos10b, Kevin Costello gives a
construction
of the Witten genus via his notion of a quantum field theory. The
goal of this seminar will be to develop enough machinery to understand
the
proof of this theorem, and try to grasp some of it�s implications
for physicallymotivated
mathematics.
