+\begin{abstract}
+Given an $n$-manifold $M$ and an $n$-category $\cC$, we define a chain complex
+(the ``blob complex") $\bc_*(M; \cC)$.
+The blob complex can be thought of as a derived category version of the Hilbert space of a TQFT, 
+or as a generalization of Hochschild homology to $n$-categories and $n$-manifolds.
+It enjoys a number of nice formal properties, including a higher dimensional
+generalization of Deligne's conjecture about the action of the little disks operad on Hochschild cochains.
+Along the way, we give a definition of a weak $n$-category with strong duality which
+is particularly well suited for work with TQFTs.
