Well, the math for QFT isn’t on as clear cut foundations as it could be either, is my understanding.
(No one has proven that there is a 3D QFT for anything more than U(1), iirc? Or maybe even for U(1) ? Idr. There’s a prize for showing one iirc.)
I don’t think that contradicts the claim of the mathematical beauty motivating things.
- ogogmad 5y agoThere aren't any definitive equations of string theory AFAICT. For the Standard Model, there are. This is on top of the lack of rigour that's already in QFT. The result is a theory that isn't really mathematics as mathematicians understand it, and nor is it physics as many physicists understand it.
