Characteristic classes in deformation quantization
arXiv:1208.4249 · doi:10.1093/imrn/rnu136
Abstract
In deformation quantization one can associate five characteristic functions to (stable) formality morphisms on cochains and chains and to "two-brane" formality morphisms. We show that these characteristic functions agree.
