Talk:Mathematical formalism of gauge theory

Correction
It's not true that the sections of a principal bundle form a group! So, this is not a good definition of the group of gauge transformations. I was confused about this for a long time myself. To get a group, you need the sections of the bundle associated to the principal bundle P by means of the adjoint action of G on itself. I don't have the energy to write a clear explanation of this for people who don't know this sort of stuff. But, I wanted to point out that the description of gauge transformations as sections of a principal bundle is wrong.

(I'll be amazed if this correction actually shows up;I have no clue how Wiki works. Sorry!)

The material in this article used to be in Gauge theory. Some of the old, archived talk page material at Talk:Gauge_theory/Archive_1 is actually about material that is now in this article, and is therefore very relevant.--76.167.77.165 (talk) 00:40, 9 August 2009 (UTC)
