Integrable models associated with Myers-Perry-AdS-dS black hole in diverse dimensions

Myers-Perry-AdS-dS black hole exhibits SO(2,1)xU(n) symmetry in the near horizon limit in the special case that all rotation parameters are equal. We consider a massive relativistic particle propagating on such a background and reduce it to superintegrable spherical mechanics with U(n) symmetry. A complete set of functionally independent u(n) generators realized in the model is given.
