Abstract.
In this talk, we want to present the basic ideas and tools of formal deformation quantization and develop the concept of symmetries in this setting, which are described by Lie algebras. Afterwards, we want to construct a deformation quantization of an algebra where a given Lie algebra acts on via a Fedosov-like construction. In this approach the concept of Drinfel'd twists appears in a natural way. Therefore, we give an introduction to this theory and use it for our approach.
