There are also interesting rules involving the spin-1 representation, which imply some highly nonobvious results. For example, every planar graph with three edges meeting at each vertex, no edge-loops, and every edge labeled by the spin-1 representation 1 • • • 1 1 1 1 • 1 • 1 • 1 1 • 1 1 1 1 • • 1 • 1 evaluates to a nonzero number [189]. But Penrose showed that this fact is equivalent to the four-color theorem! By now, Penrose’s diagrammatic approach to the finite-dimensional representations of SU(2) has been generalized to many compact simple Lie groups.

The pentagon and triangle identities are the least obvious part of this definition—but also the truly brilliant part. The point of the pentagon identity is that when we have a tensor product of four objects, there are five ways to parenthesize it and, at first glance, the associator gives two different isomorphisms from w ⊗ (x ⊗ (y ⊗ z)) to ((w ⊗ x) ⊗ y) ⊗ z. The pentagon identity says these are in fact the same! Of course, when we have tensor products of even more objects, there are even more ways to parenthesize them and even more isomorphisms between them built from the associator.

We can see any group G as a category with one object in which all the morphisms are invertible; the morphisms of this category are just the elements of the group, whereas composition is multiplication. There is also a category Hilb, in which objects are Hilbert spaces and morphisms are linear operators. A representation of G can be seen as a map from the first category to the second: ρ : G → Hilb. Such a map between categories is called a functor. The functor ρ sends the one object of G to the Hilbert space H , and it sends each morphism g of G to a unitary operator ρ(g) : H → H .
