Re: additive 2-categories and related structures?

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. David On 29 August 2010 19:31, Ronnie Brown <ronnie.profbrown@btinternet.com> wrote:

 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.
