Abstract
Recently the author proved that the Hummel–Scheinberg–Zalcman conjecture of 1977 on coefficients of nonvanishing Hp functions is true for all p = 2m, m ϵ ℕ, i.e., for the Hilbertian Hardy spaces H2m. As a consequence, this also implies the proof of the Krzyz conjecture for bounded nonvanishing functions, which originated this direction.
In the present paper, we solve the problem for all spaces Hp with p ≥ 2.
