Duality in Boij--Soederberg Theory
Abstract: The central idea in Boij-Soederberg Theory is that there is
a connection between free resolutions over the polynomial ring and
sheaf cohomology on projective space. I'll provide motivation for
this connection with an example, looking at properties of the long
exact sequence in sheaf cohomology from a new perspective. Then I'll
describe the construction of a duality pairing that leads to precise
duality results relating free resolutions and sheaf cohomology. This
is joint work with David Eisenbud.
