Hopf algebroid twists in deformation quantization

Ping Xu has shown that every deformation quantization leads to a Drinfeld twist of the associative bialgebroid of differential operators on the Poisson manifold. In a different approach, we obtained with S. Meljanac explicit formulas for twisted Hopf algebroid structures in several simplest examples, including thorough understanding in the case of linear Poisson structures.
