Abstract:   The Buchsbaum-Eisenbud-Horrocks rank conjecture roughly says that the Koszul complex is the "smallest possible" free resolution of a graded module. Although Boij-Soederberg theory is based on the principle of only considering Betti diagrams up to scalar multiple, I will explain how the structure of Boij-Soederberg theory is sufficiently strong to prove new cases of the Buchsbaum-Eisenbud-Horrocks rank conjecture.
