Algebra & Combinatorics Seminar

Title: Rings with several objects
Speaker: Abhishek Banerjee (IISc Mathematics)
Date: 16 November 2018
Time: 3 pm
Venue: LH-1, Mathematics Department

An ordinary ring may be seen as a preadditive category with just one object. This leads to the powerful analogy, first formulated explicitly by Mitchell in 1975, that a small preadditive category should be seen as a “ring with several objects”. We will trace the history and development of the category of modules over a preadditive category.
