Title: Classification of smooth Hilbert schemes.
Abstract: The Hilbert scheme parametrizing closed subschemes in a fixed
projective n-space having Hilbert polynomial p is a projective scheme.
Each such polynomial p can be described in terms of an integer partition,
and this can then be used to classify which Hilbert schemes are smooth.
The corresponding subschemes parametrized are described by a
generalization of partial flags. I will try to explain the classification
result and the underlying geometry. These new results are based on a joint
work with Greg Smith.
