Abstract: We extend norm estimates of composition operators of Michael Jury in 2007 on weighted Hardy and Bergman spaces of the unit ball to more general reproducing kernel spaces on the unit ball and the polydisk, for example, on the Dirichlet space of the unit ball and the Hardy space of the polydisk. For the composition operators with affine symbols on the unit ball, we find their exact norms which extend the corresponding results of Cowen in 1988 and Hurst in 1997.
