Abstract
We consider the family of Toeplitz operators T_(JS[overbar]^a) acting in the Hardy space H^2 in the upper halfplane; J and S are given meromorphic inner functions, and a is a real parameter. In the case where the argument of S has a power law type behavior on the real line, we compute the critical value c(J, S) = inf{a: ker T_(JS[overbar]^a) ≠ 0} The formula for c(J,S) generalizes the Beurling-Malliavin theorem on the radius of completeness for a system of exponentials.
