@ CAT SEMINAR

Speaker: Robert Paré (Dalhousie University)

Title: Morphisms of Rings

Abstract: 

I will look at the double category of rings with homomorphisms and bimodules as a motivating example of double category. I will discuss companions and conjoints. This will lead to “new" morphisms of rings which I think are interesting.

Prerequisites:
Some familiarity with rings, modules, and categories.
