I've realized over the past few days just how important gauge theories and Lie algebras are in physics. Like, I knew they were important, but they're everywhere. I really need to learn group theory, and brush up on my linear algebra.

Can the number of dimensions in an effective theory depend on the lengthscale/energyscale where it is defined? In other words, can d be running due to RG flow?
