= Chern–Simons form
{wiki=Chern–Simons_form}
The Chern–Simons form is a mathematical construct that arises in differential geometry and theoretical physics, particularly in the study of gauge theories and topology. It is named after the mathematicians Shiing-Shen Chern and James Simons. In essence, the Chern–Simons form is a differential form associated with a connection on a principal bundle, and it helps in the definition of topological invariants of manifolds, notably in the context of 3-manifolds.
