Abstract
is said to be in V(θn) if the analytic and univalent function f in the unit disc E is nozmalised by f(0) = 0, f′(0) = 1 and arg an = θn for all n. If further there exists a real number β such that θn + (n − 1)β ≡ π(mod2π) then f is said to be in V(θn, β). The union of V(θn, β) taken over all possible sequence {θn} and all possible real number β is denoted by V. Vn(A, B) consists of functions f ∈ V such that urn:x-wiley:01611712:media:ijmm453427:ijmm453427-math-0002 −1 ≤ A < B ≤ 1, where n ∈ NU{0} and w(z) is analytic, w(0) = 0 and |w(z)| < 1, z ∈ E. In this paper we find the coefficient inequalities, and prove distortion theorems.
