The topic for Math 206 this quarter is the Hilbert scheme of
points on surfaces.
In the beginning of the course, we will construct the Hilbert scheme
in full generality. This is important for a number of moduli problems in
algebraic geometry.
For the Hilbert scheme of points on surfaces, we will compute some
of the topological invariants. In particular, we express the Euler
characteristics in terms of modular forms. Connections with the
representation theory of affine Lie algebras will be made.
(This may be a bit too ambitious for a one quarter course, so the
goals
may change slightly as we go.)
