    Abstract

    Let (Formula presented.) be linearly independent over (Formula presented.), and set (Formula presented.) We prove sharp estimates for the growth of a polynomial of degree n, in terms of (Formula presented.)where (Formula presented.) is the unit polydisk. For all (Formula presented.) with linearly independent entries, we have the lower estimate (Formula presented.)for Diophantine (Formula presented.), we have (Formula presented.)In particular, this estimate holds for almost all (Formula presented.) with respect to Lebesgue measure. The results here generalize those of Coman and Poletsky [6] for (Formula presented.) without relying on estimates for best approximants of rational numbers which do not hold in the vector-valued setting.
