Then we're applying two different operators. The Einstein projection operator is zeroth order, it's destructive in the sense that it doesn't see the entire curvature tensor. The adjoint exterior derivative operator is inclusive but of first order. | Then we're applying two different operators.

A problem is that the hallmark of the Yang-Mills theory is the freedom to choose the data, the internal quantum numbers that give all the particles their personalities beyond the mass and the spin. We can allow the gauge group of symmetries to act on both sides of the equation, but the key problem is that: $$P_E(F_{\Delta^LC h}) \neq h^{-1} P_E(F_{\Delta^LC }) h $$. If I act on connections on the right and then take the Einstein projection, this is not equal to first taking the projection and then conjugating with the gauge action. So the problem is, is that the projection is based on the fact that you have a relationship between the intrinsic geometry. If this is an ad-valued two-form, the two-form portion of this and the adjoint portion of this are both associated to the structure group of the tangent bundle. | |||
