Remark 3.16. The behavior of a homology theory with coefficients in depends critically on the symmetric monoidal structure chosen on . For instance, for the symmetric monoidal -category of -modules over a fixed field with direct sum, a homology theory is forced to be ordinary homology with coefficients in ; while for , a homology theories is typically not a homotopy invariant of manifolds.
