category with duals (list of them)
dualizable object (what they have)
ribbon category, a.k.a. tortile category
monoidal dagger-category?
Any braided monoidal category has a natural isomorphism
called the braiding.
A braided monoidal category is symmetric if and only if and are inverses (although they are isomorphisms regardless).
In Vect or Mod, the braiding maps elements of a tensor product of modules to .
For the tensor product of chain complexes or that of super vector spaces there is in addition a sign .
For more see at signs in supergeometry.
