additive 2-categories and related structures?

additive 2-categories and related structures?

[Ronnie Brown]

   I would be grateful for information on published or available work in
this area.

I am thinking of an additive category as a ring with several objects, as
in Mitchell's well known paper. So in a sense am looking at 2-rings.

Thanks in anticipation.

Hi Ronnie,

There is the work of Matthieu Dupont, see his page

http://breckes.org/dom-en.html

His PhD thesis is on abelian categories in dimension 2.

Dear Ronnie,

only just saw your message via David's reply.

Just for completeness it seems one should say that there is quite a
bit known about additive n-categories even for n all the way from 1 to
infinity -- they are called stable infinity-categories. Examples of
these are in particular given by modules over infinity-rings -- which
are maybe better known as ring spectra!

A modern entry point into the theory, from a category-theoretic point of view is

Jacob Lurie
Commutative algebra
http://arxiv.org/abs/math/0703204

But the basic elements and examples of the theory, such as
E-infinity-rings, A-infinity-algebras and their modules and module
categories are of course way older and quite classical even.

All the best
Urs

Dear Ronnie,

You can find many good things in Mathieu Dupont's PhD thesis:
