The value of a theory of non-abelian gerbes?

20 views

How valuable for physics and math would be a description of a quantum field theory of non-abelian gerbes? If one could derive the instanton-part of the AGT-correspondence as a low-energy duality from such a theory would that be a sufficient prove?
