Added reference to a generalization of the Karoubi envelope for n-categories in
Very interesting to see a physicist like Davide Gaiotto coauthor an article with some substantial abstract category theory in it.
Hayashi says that Karoubi introduced this construction in K-Theory, but I haven’t tried to find where exactly it is introduced (and under what name).
Thanks! (For bystanders: This comes from discussion in another thread, here)
I have added the full publication data

Looks to me like Hayashi must have been thinking of Teorem 6.10 in Karoubi’s “K-theory”. I’ll add the pointer to the entry now…
After “appears to have been introduced in…” I have now added:
… apparently in reference to the construction in:
