## Commutative Algebra Seminar2:30pm - Vincent Hall 209Global Sections of Toric Vector Bundles Jorin Schug This talk will continue to follow the "Parliament of Polytopes" paper by Di Rocco, Jabbusch, and Smith. I'll discuss the result that the T-equivariant generators for the global sections of a toric vector bundle E correspond to the lattice points in the parliament of polytopes for E and look to understand this result for some examples, including direct sums of line bundles. |

## Commutative Algebra Seminar2:30pm - Vincent Hall 209Linkage, and the licci conjecture on grade 3 perfect ideals Mahrud Sayrafi, University of Minnesota Let Q be a regular local ring. An ideal I in Q is said to be licci if it is in the linkage class of a complete intersection. Christensen, Veliche and Weyman conjectured that a perfect ideal of grade 3 in Q is licci if and only if its free resolution corresponds to Dynkin diagrams. After introducing the theory of linkage, I will talk about the conjecture, how Dynkin diagrams are involved, and their approach in showing one direction of the conjecture in arXiv:1712.04016. |

## Commutative Algebra Seminar2:30pm - Vincent Hall 209The spectral sequence of a filtered complex Gennady Lyubeznik, University of Minnesota This is the third of a series of three talks on the spectral sequence of a filtered complex. This material is by now classical and is an important part of homological algebra. The main difficulty in dealing with spectral sequences is that there are a lot of indexes involved and this is a considerable obstacle to understanding what is going on. The goal of these talks is to present this material, including most proofs, in an accessible manner. |
