 \section{Deligne conjecture for $n$-categories}
 \label{sec:applications}
 
+Let $M$ and $N$ be $n$-manifolds with common boundary $E$.
+Recall (Theorem \ref{thm:gluing}) that the $A_\infty$ category $A = \bc_*(E)$
+acts on $\bc_*(M)$ and $\bc_*(N)$.
+Let $\hom_A(\bc_*(M), \bc_*(N))$ denote the chain complex of $A_\infty$ module maps
+from $\bc_*(M)$ to $\bc_*(N)$.
+Let $R$ be another $n$-manifold with boundary $-E$.
+There is a chain map
+\[
+	\hom_A(\bc_*(M), \bc_*(N)) \ot \bc_*(M) \ot_A \bc_*(R) \to \bc_*(N) \ot_A \bc_*(R) .
+\]
+We think of this map as being associated to a surgery which cuts $M$ out of $M\cup_E R$ and
+replaces it with $N$, yielding $N\cup_E R$.
+
+Recall (Theorem \ref{thm:evaluation}) that chains on the space of mapping cylinders also act  on the 
+blob complex.
