Abstract

We prove that there is a continuous non-negative function gg on the unit sphere in \cd\cd, d2d \geq 2, whose logarithm is integrable with respect to Lebesgue measure, and which vanishes at only one point, but such that no non-zero bounded analytic function mm in the unit ball, with boundary values mm^\star, has mg|m^\star| \leq g almost everywhere. The proof analyzes the common range of co-analytic Toeplitz operators in the Hardy space of the ball.
