\begin{theorem}

{\mathbf Grothendieck's theorem}: Every $𝒜b5$ category with a generator has an injective cogenerator (Grothendieck 1957). \end{theorem}

This initial statement of Grothendieck's theorem is now restated as: \begin{theorem} Every [[../GrothendieckCategory/|Grothendieck category]] $𝒢$ has an [[../BCConjecture/|injective]] cogenerator. \end{theorem}
