In this paper, we prove that for a function such that 1 y z f z ª 0 as z ª 1 and for large z , f z s o z for some k, the Taylor coefficients a have the integral representation n

Abstract
In this paper we introduce the class of differentiable weights ω in the unit disc 𝔻 such that
equation image
where L is a positive constant.
The main result in this paper asserts that if ω is one of these weights, then the equivalence
equation image
holds for all 0 < p < ∞, 0 < q ≤ ∞and f an analytic function in 𝔻. 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)

The approximation of the Voigt line shape by the linear summation of Lorentzian and Gaussian line shapes of equal width is well documented and has proved to be a useful function for modeling in vivo 1 H NMR spectra. We show that the error in determining peak areas is less than 0.72% over a range of
A computer program has been developed that calculates, using the weighted least-squares technique, the overall formation constants, Bi, of mononuclear complexes, the standard deviations of Bi, SDV,, and an estimate of goodness of fit, Goodness-of-Fit Parameter (GOFP), given a set of average ligand n
