Reconstruction of universal Drinfeld twists from representations
Christian Blohmann
Universal Drinfeld twists are inner automorphisms which relate the coproduct of a quantum enveloping algebra to the coproduct of the undeformed enveloping algebra. Even though they…

Perturbative Symmetries on Noncommutative Spaces
Christian Blohmann
Perturbative deformations of symmetry structures on noncommutative spaces are studied in view of noncommutative quantum field theories. The rigidity of enveloping algebras of semi-…

Realization of q-deformed spacetime as star product by a Drinfeld twist
Christian Blohmann
Covariance ties the noncommutative deformation of a space into a quantum space closely to the deformation of the symmetry into a quantum symmetry. Quantum deformations of envelopin…
