In this paper we introduce the class of differentiable weights ω in the unit disc such thatwhere L is a positive constant. The main result in this paper asserts that if ω is one of these weights, then the equivalenceholds for all 0 < p < ∞, 0 < q ≤ ∞and f an analytic function in . Our results improve others due to Aleman, Siskakis, and Stević. We also prove two results on harmonic conjugate functions. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
