 One approach to such a generalization might be to simply define a
 TQFT via its gluing formulas, replacing tensor products with
-derived tensor products.
-\nn{maybe cite Kh's paper on links in $S^1\times S^2$}
+derived tensor products (c.f. \cite{1011.1958}).
 However, it is probably difficult to prove
 the invariance of such a definition, as the object associated to a manifold
 will a priori depend on the explicit presentation used to apply the gluing formulas.
