Twists of quantum groups and noncommutative field theory
arXiv:hep-th/0606056
Abstract
The role of quantum universal enveloping algebras of symmetries in constructing a noncommutative geometry of space-time and corresponding field theory is discussed. It is shown that in the framework of the twist theory of quantum groups, the noncommutative (super) space-time defined by coordinates with Heisenberg commutation relations, is (super) Poincaré invariant, as well as the corresponding field theory. Noncommutative parameters of global transformations are introduced.
