Quantum Anti-de Sitter Space at Roots of Unity
Harold Steinacker
This is a short summary of the paper hep-th/9910037. An algebra of functions on q-deformed Anti-de Sitter space AdS_q^D is defined for q a root of unity, which is covariant under U…
Decoupling Braided Tensor Factors
Gaetano Fiore, Harold Steinacker, Julius Wess
We briefly report on our result that the braided tensor product algebra of two module algebras of a quasitriangular Hopf algebra is equal to the ordinary tensor produ…
Unbraiding the braided tensor product
Gaetano Fiore, Harold Steinacker, Julius Wess
We show that the braided tensor product algebra of two module algebras of a quasitriangular Hopf algebra is equal to the ordinary tensor…
Propagator on the h-deformed Lobachevsky plane
John Madore, Harold Steinacker
The action of the isometry algebra U_h(sl(2)) on the h-deformed Lobachevsky plane is found. The invariant distance and the invariant 2-point functions are shown to agree precisely…
Unitary Representations of Noncompact Quantum Groups at Roots of Unity
Harold Steinacker
Noncompact forms of the Drinfeld-Jimbo quantum groups U_q(g) with (H_i)* = H_i, (X_i^{+-})* = s_i X_i^{-+} for s_i= +-1 are studied at roots of unity. This covers g = so(n,2p), su(…
Convergent Perturbation Theory for a q-deformed Anharmonic Oscillator
Rainer Dick, Andrea Pollok-Narayanan, Harold Steinacker +1
A --deformed anharmonic oscillator is defined within the framework of --deformed quantum mechanics. It is shown that the Rayleigh--Schrödinger perturbation series for the bou…
