Quantum deformations of the flat space superstring
Anna Pachol, Stijn J. van Tongeren
We discuss a quantum deformation of the Green-Schwarz superstring on flat space, arising as a contraction limit of the corresponding deformation of AdS_5 x S^5. This contraction li…

Twisted conformal algebra related to -Minkowski space
Stjepan Meljanac, Anna Pachol, Danijel Pikutic
Twisted deformations of the conformal symmetry in the Hopf algebraic framework are constructed. The first one is obtained by a Jordanian twist built up from dilatation and momenta…

-Minkowski star product in any dimension from symplectic realization
Anna Pachol, Patrizia Vitale
We derive an explicit expression for the star product reproducing the -Minkowski Lie algebra in any dimension . The result is obtained by suitably reducing the Wick-Voros sta…
