3:45PM: Annihilators of cohomology for modules over a commutative ring

Srikanth Iyengar

This talk concerns the following question, raised by Craig Huneke: Given an affine algebra R of Krull dimension d, does the Jacobian ideal of R annihilate Ext^{d+1}_R(M,N) for all finitely generated R-modules M and N? The focus of my talk will be to explain why I find this question interesting and to report on recent progress on it. This work is part of an on-going collaboration with Ryo Takahashi, some of which is reported in the preprint arXiv: arXiv:1610.02599
