Kontsevich graphs act on Nambu-Poisson brackets, III. Uniqueness aspects

Floor Schipper, Mollie S Jagoe Brown, Arthemy V Kiselev

Kontsevich constructed a map between `good' graph cocycles $I^^{3}$ and infinitesimal deformations of Poisson bivectors on affine manifolds, that is, Poisson cocycles in the second Lic…

Kontsevich graphs act on Nambu--Poisson brackets, II. The tetrahedral flow is a coboundary in 4D

Mollie S. Jagoe Brown, Floor Schipper, Arthemy V. Kiselev

Kontsevich constructed a map from suitable cocycles in the graph complex to infinitesimal deformations of Poisson bi-vector fields. Under the deformations, the bi-vector fields rem…

Kontsevich graphs act on Nambu-Poisson brackets, I. New identities for Jacobian determinants

Arthemy V. Kiselev, Mollie S. Jagoe Brown, Floor Schipper

Nambu-determinant brackets on $R^{d} ∋ x = (x^{1}, ..., x^{d})$ , ${f, g}_{d} (x) = I ¨ (x) det (\partial (f, g, a_{1}, ..., a_{d - 2}) / \partial (x^{1}, ..., x^{d}))$ , with $a_{i} \in C^{\infty} (R^{d})$ and $Ï\partial_…
