Aug 20, 2020 · Closed subschemes in projective space with a fixed Hilbert polynomial are parametrized by a Hilbert scheme. We classify the smooth ones. We identify numerical conditions on a polynomial that completely determine when the Hilbert scheme is smooth.

ROY SKJELNES: The Grassmannians are generalizations of projective spaces, and their cohomology ring is known. Understanding these objects gives a glimpse into both classical and modern algebraic geometry. The project is to define the Grassmannians and Schubert cells, and to understand the intersection theory on the Grassmannian.
