Characteristic classes in deformation quantization


Willwacher, Thomas (2015). Characteristic classes in deformation quantization. International Mathematics Research Notices, 2015(15):6538-6557.

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.
