The orientation morphism: from graph cocycles to deformations of Poisson structures
Ricardo Buring, Arthemy Kiselev
We recall the construction of the Kontsevich graph orientation morphism which maps cocycles in the non-oriented graph complex to infinitesimal symm…

The heptagon-wheel cocycle in the Kontsevich graph complex
Ricardo Buring, Arthemy Kiselev, Nina Rutten
The real vector space of non-oriented graphs is known to carry a differential graded Lie algebra structure. Cocycles in the Kontsevich graph complex, expressed using formal sums of…
