Is there a classification of symmetric monoidal closed structures on $\mathbf{Ab}$?

126 Views Asked by At

How much is known/has been studied about symmetric monoidal closed structures on the category of abelian groups $\mathbf{Ab}$ up to equivalence? Is there any nice characterization of the usual tensor product of abelian groups among these?

There is exactly one (symmetric) closed monoidal structure on the category of abelian groups (up to equivalence). This is Proposition 3 of Foltz–Lair–Kelly's Algebraic categories with few monoidal biclosed structures or none.
