 This result is described in more detail as Example 6.2.8 of \cite{1009.5025}.
 
-%Fix a topological $n$-category $\cC$, which we'll now omit from notation.
-%Recall that for any $(n-1)$-manifold $Y$, the blob complex $\bc_*(Y)$ is naturally an $A_\infty$ category.
-The $A_\infty$ actions above allow us to state a gluing theorem.
-For simplicity, we omit the $n$-category $\cC$ from the notation.

 We next describe the blob complex for product manifolds, in terms of the $A_\infty$ blob complex of the $A_\infty$ $n$-categories constructed as above.
