Affine group schemes over symmetric monoidal categories

... One of the most important results in the study of group schemes is the following, presented in [Tate and Oort 1970]. Theorem 1.1 (Deligne’s lemma). Let G = Spec(A) be an affine commutative group scheme over a commutative, Noetherian ring k. Assume that A is a flat k-algebra of rank r ≥ 1. Then, for ...
