## Quantization

### Idea

Quantum groups were introduced independently by Drinfeld and Jimbo around 1984. One of the most important examples of quantum groups are deformations of universal enveloping algebras. These deformations are closely related to Lie bialgebras. In particular, every deformation of a universal enveloping algebra induces a Lie bialgebra structure on the underling Lie algebra. In (Drinfeld) Drinfeld asked if the converse of this statement holds:

“Does there exist a universal quantization for Lie bialgebras?”

This was answered to the positive in (Etingof-Kazhdan).
