Coefficient Estimates for α-λ Sprial-Like Functions of Order β

Let α≥ 0, 0 ≤β< 1, |λ| < π/2 and suppose that f(z) = z + is said to be α- λsprial-like of order β if it satisfies Re {(eiλ- α) zf (z)/f(z) + α(1+zf (z)/f (z)). In this study we determine sharp bounds for the moduli |an| of the coefficients.
