ヤン＝ミルズ理論
The above development generalizes in a more-or-less straightforward fashion to general principal "G"-bundles for some arbitrary Lie group "G" taking the place of U(1). In such a case, the theory is often referred to as a Yang–Mills theory, and is sometimes taken to be synonymous. If the underlying manifold is supersymmetric, the resulting theory is a super-symmetric Yang–Mills theory.
