%0 Journal Article %T Quantum Co-Adjoint Orbits of the Real Diamond Group %A Nguyen Viet Hai %J Mathematics %D 2000 %I arXiv %X We present explicit formulas for deformation quantization on the co-adjoint orbits of the real diamond Lie group. From this we obtain quantum half-plans, quantum hyperbolic cylinders, quantum hyperbolic paraboloids via Fedosov deformation quantization and finally, the corresponding unitary representations of this group. %U http://arxiv.org/abs/math/0001046v2
