摘要：

We give a convex description of the Schur-Agler norm for holomorphic functions on the polydisk. With the convex description, we are able to realize the predual Schur-Agler space as an analytic function space on the polydisk. We give a uniform approach to existing counterexamples of the von Neumann's inequality and generalize it, resulting two lower bounds of the Schur-Agler norm, which has the form of weak products. We show that these lower bound norms are equivalent to the Hardy norm. Two new proofs of existing results are also given. Some numerical applications are also given. This is joint work with Michael Hartz.
