WebSep 13, 2024 · A Chern-Simons form CS(A) is a differential form naturally associated to a differential form A ∈ Ω1(P, 𝔤) with values in a Lie algebra 𝔤: it is the form trivializing (locally) a curvature characteristic form FA ∧ ⋯ ∧ FA of A, for ⋯ an invariant polynomial: ddRCS(A) = FA ∧ ⋯ ∧ FA , where FA ∈ Ω2(X, 𝔤) is the curvature 2-form of A.
