Gauge Invariance of the Non-abelian Chern-Simons Term Gauge invariance of the Abelian Chern-Simons term Другие результаты с сайта physics.stackexchange.com

The coefficient k is sometimes called the level of the Chern-Simons term. At first glance, it's not obvious that the Chern-Simons term is gauge invariant since.

The gauge invariance and the metric invariance can be viewed as the invariance under the adjoint Lie group action in the Chern–Weil theory. The action integral ...
