## 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. |

## Commutative Algebra Seminar12:20pm - Vincent Hall 213On a question of Dutta, joint with Linquan Ma and Anurag Singh Uli Walther, Purdue For a local ring (A,m) of dimension n,we study the natural map from the n-th Koszul cohomology on a minimal set of generators of m to the top local cohomology of A supported at m. We construct complete normal domains for which this map is zero, thus answering a question of Dutta in the negative. If time permits, we present precise information on the kernel of this map for a large class of Stanley-Reisner rings. |

## Commutative Algebra Seminar12:20pm - Vincent Hall 213Tate Resolutions and Horrocks Splitting Criterion Mahrud Sayrafi , I will talk about the two papers Eisenbud-Fløystad-Schreyer-2003 and Eisenbud-Erman-Schreyer-2015 in which they introduce Tate resolutions for projective spaces and products of projective spaces. As an application, I will talk about Horrocks' criterion for vector bundles in those settings. |

## Commutative Algebra Seminar12:20pm - Vincent Hall 213$\tau$-Factorization and $\tau$-Elasticity Bethany Kubik, University of Minnesota, Duluth A more generalized form of factorization, called $\tau$-factorization, was introduced in 2011 by D.D. Anderson and J. Reinkoester. In $\tau$-factorization, all factors of a factorization must belong to the same equivalence class modulo a fixed ideal. We discuss $\tau$-factorization in small settings and $\tau$-elasticity in a more general setting. |
