Abstract
We prove that there is a continuous non-negative function on the unit sphere in , , 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 in the unit ball, with boundary values , has almost everywhere. The proof analyzes the common range of co-analytic Toeplitz operators in the Hardy space of the ball.
