Object: What corresponds to intertwing operators?
Hello Hello,
If particles correspond to irreducible representations,
what corresponds to morphisms between irreducible
representations?
According to Schur's lemma they are either trivial
or isomorphisms. What do they correspond to physically?
Help!

Interactions! The vertices in Feynman diagrams are intertwiners.
A good place to read about this stuff is in the quantum gravity
notes at John Baez's website.
