 We will call instances of our definition ``disk-like $n$-categories", since $n$-dimensional disks
 play a prominent role in the definition.

 For 2-categories, ``pivotal" is a standard term for what we mean.

 We sometimes refer to this as ``strong duality", and sometimes we consider it to be implied

 Finally, we need a general name for isomorphisms between balls, where the balls could be
 piecewise linear or smooth or topological or Spin or framed or etc., or some combination thereof.
