Title: Linear strands of multigraded free resolutions (Part 1)

Abstract: The linear strand of a free resolution F over a standard graded polynomial ring is, roughly speaking, the subcomplex of F determined by the first row of its Betti table. Over polynomial rings with non-standard gradings, this definition is no longer sensible, because linearity (suitably interpreted) cannot be detected in terms of Betti numbers. I will discuss a theory of linear strands of free resolutions over polynomial rings with non-standard gradings that manages to avoid this problem, as well as some geometric motivation for such a theory. This is joint work with Daniel Erman.

Title: Linear strands of multigraded free resolutions (Part 2)
