Title: Noetherianity and Ext

Abstract: This talk is designed to introduce non-experts to both noetherianity and to cohomology. Noetherianity has played a central role in algebra and geometry since it was introduced by Emmy Noether. I will briefly review basic concepts and some fundamental results. Cohomology was introduced in algebraic topology in 1920's and 1930's (DeRahm and Cech cohomology for example). The use of cohomology has become a standard tool in studying algebraic structures such as groups, rings, and modules. I will briefly give an introduction to the theory of the cohomology of rings. At the end of the talk I will touch on some recent work of Nicole Snashall, Oeyvind Solberg, Dan Zacharia and myself connecting these ideas.

Place: Science and Technology Building I, Room 242

Refreshments will be served before the talk at 3:00 p.m. in Room 222.
