Frobenius category

From Wikipedia, the free encyclopedia

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

[edit]

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