Can someone explain how the wormhole motion is valid as a diffeomorphism, which my limited understanding suggests is the only permitted type of manifold transformation in relativity. Diffeomorphisms are about coordinate transformations, and have nothing to do with anything physical. If, in a coordinate patch, you switch to a different coordinate system, ...

A conformal field theory is a quantum field theory which is invariant under conformal transformations. Due to this invariance, correlation functions must obey linear equations called conformal Ward identities. Conformal blocks are not just solutions of the conformal Ward identities, but actually elements of a particular basis of solutions. Let us focus on ...

There may be some language confusion here. The "Majorana representation" refered to in the question has nothing to do with Majorana fermions. Rather it is about the so-called "Majorana stellar representation" of spin J pure quantum states (which can be thought of as the generalization for J>1/2 of the Bloch representation of spin 1/2 pure states). See e.g. ...
