Wheels in deformation quantization
In this talk, we will discuss the appearance of directed cycles (graphs with wheels) in Kontsevich's deformation quantization formula for a Poisson structure,
and show that any universal formula necessarily involves wheels.
We will conclude by sketching how the wheels can be absorbed
in a deformation of the Poisson structure.
