I am currently pursuing my PhD degree under the joint supervision of Prof. Rudolph (Leipzig, Germany) and Prof. Huebschmann (Lille, France).
My research is motivated by conceptual and mathematical problems of classical field theory, which I try to attack with infinite-dimensional differential geometry. In particular, I am interested in the action of Fréchet Lie groups on Fréchet manifolds to investigate the moduli spaces occurring as configuration spaces of gauge theory and general relativity.

Connection and reduction of the structure group
To show that there are $H$-compatible connections on $E$, it seems to be a bit easier to take an arbitrary connection on the reduced bundle and then extend it to the original bundle. |

Curvature of a principal bundle and the exterior covariant derivative
You can try Kobayashi, Nomizu "Foundations of Differential Geometry". Their approach is essentially the same through their notation is different. |

Yang-Mills Functional and Energy
Yes of course you are right, my answer applies only in the Riemannian case. But as you noted, for Minkowski spacetime the norm of the curvature is not the Hamiltonian but the Lagrangian. Thus in this case the question does not make much sense. |

Smooth curves in a Frechet space
No problem! It is common here on mathoverflow to mark responses as answers if they satisfy your needs (in order to declare such questions as answered). On the other hand, if you still have open questions, I'm more than happy to expand my answer. |
