In \S \ref{sec:ainfblob} we give an alternative definition
of the blob complex for an $A_\infty$ $n$-category on an $n$-manifold (analogously, using a homotopy colimit).
Using these definitions, we show how to use the blob complex to ``resolve" any topological $n$-category as an

The definitions presented below tie the categories more closely to the topology
and avoid combinatorial questions about, for example, the minimal sufficient
collections of generalized associativity axioms; we prefer maximal sets of axioms to minimal sets.

Conversely, one can show that a topological $A_\infty$ $n$-category $\cC$, where the $k$-morphisms
