Abstract
We recall the construction of the Kontsevich graph orientation morphism which maps cocycles γ in the non-oriented graph complex to infinitesimal symmetries of Poisson bi-vectors on affine manifolds. We reveal in particular why there always exists a factorization of the Poisson cocycle condition through the differential consequences of the Jacobi identity for Poisson bi-vectors . To illustrate the reasoning, we use the Kontsevich tetrahedral flow , as well as the flow produced from the Kontsevich–Willwacher pentagon-wheel cocycle γ5 and the new flow obtained from the heptagon-wheel cocycle γ7 in the unoriented graph complex.
Highlights
On an affine manifold M r, the Poisson bi-vector fields are those satisfying the Jacobi identity [[P, P]] = 0, where [[·, ·]] is the Schouten bracket [12, see Example 1 below]
We reveal in particular why there factorization of the Poisson cocycle condition [[P, O⃗r(γ)(P)]] =. 0 through the differential consequences of the Jacobi identity [[P, P]] = 0 for Poisson bi-vectors P
We use the Kontsevich tetrahedral flow P = O⃗r(γ3)(P), as well as the flow produced from the Kontsevich–Willwacher pentagon-wheel cocycle γ5 and the new flow obtained from the heptagon-wheel cocycle γ7 in the unoriented graph complex
