What is gauge theory? What is a gauge? Manifolds and topological spaces make my brain hurt. Why can't it be simple instead of tensor wank with complex numbers?

What's the simplest gauge out there?

Bruh, principal bundles aren't that hard. Just make sure you have a good grasp of connection forms in Riemannian differential geometry, then the generalization to Lie algebra valued forms will be straightforward. Abstractly it really is as simple as it can be. Only the actual calculations might be tedious. And the quantum mechanical consequences of gauge theory are definitely worth it. After all, you get a possible explanation for free will, getting us one step closer to solving the hard problem of consciousness.

Theory with gauges
>What is a gauge?
a choice of coordinates in an abstract sense
>What's the simplest gauge out there?
U(1) in some sense, but the anomaly cancellation problem in general produces a set of diophantine equations, which is a massive pain

False. The simplest gauge is the trivial gauge on the principal bundle with group {0}.

As said. I'm sure.

I know. But the trivial example is also not very useful. The simplest gauge is no gauge.

Holy shit I am actually starting to get it now. Thanks
