Frobenius category

In category theory, a branch of mathematics, a Frobenius category is an exact category with enough projectives and enough injectives, where the classes of projectives and injectives coincide. It is an analog of a Frobenius algebra.

Properties

The stable category of a Frobenius category is canonically a triangulated category.[1]

gollark: Doubtful. If that worked Urban Dictionary would basically not work at all.
