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

 Another thing we need a name for is the ability to rotate morphisms around in various ways.
 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
 by ``disk-like".

+Another possibility considered here was ``pivotal $n$-category", but we prefer to preserve pivotal for its usual sense. It will thus be a theorem that our disk-like 2-categories are equivalent to pivotal 2-categories, c.f. \S \ref{ssec:2-cats}.
 
 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.
