On Burch Rings
Toshinori Kobayashi | Nagoya University, Japan
Friday, March 6 4:30 – 6 p.m. at ARM 315
Monday, March 9 4:30 – 6 p.m. at ARM 315
Abstract: I will introduce a class of ideals and their affiliated rings, which we call Burch ideals and Burch rings. While their definitions are quite simple, our investigation shows that they enjoy remarkable ideal-theoretic and homological properties. I will give some basic properties of Burch rings. Especially, a characterization of Burch rings will be given in terms of the second syzygy of the residue field. I will also talk about a classification of subcategories and trivial vanishing of Tor over these rings.
