COEFFICIENTS ESTIMATES FOR FUNCTIONS IN Bn(α)

چکیده
where Dn denotes the differential operator with Dnf(z) = D(Dn−1f(z)) = z[Dn−1f(z)]′ and D◦f(z)= f(z). Remark 1.2. The differential operator Dn was introduced by Sălăgean [5]. For n = 1, B1(α) denotes the class of Bazilević functions with logarithmic growth studied [4, 6, 7], amongst others. In [2], the author established some properties of the class Bn(α) including showing that Bn(α) forms a subclass of S, the class of all analytic, normalized, and univalent functions in D. The class B0(α) was initiated by Yamaguchi [8].

Coefficient Estimates for a General Subclass of m-fold Symmetric Bi-univalent Functions by Using Faber Polynomials
In the present paper, we introduce a new subclass H∑m (λ,β)of the m-fold symmetric bi-univalent functions. Also, we find the estimates of the Taylor-Maclaurin initial coefficients |am+1| , |a2m+1| and general coefficients |amk+1| (k ≥ 2) for functions in this new subclass. The results presented in this paper would generalize and improve some recent works of several earlier authors.
متن کاملCertain Inequalities for a General Class of Analytic and Bi-univalent Functions
In this work, the subclass of the function class S of analytic and bi-univalent functions is defined and studied in the open unit disc. Estimates for initial coefficients of Taylor- Maclaurin series of bi-univalent functions belonging these class are obtained. By choosing the special values for parameters and functions it is shown that the class reduces to several earlier known classes of analy...
متن کاملA Class of Analytic Functions Based on Convolution
We introduce a class TS p(α) of analytic functions with negative coefficients defined by convolution with a fixed analytic function g(z) = z+ P∞ n=2 bnz , bn > 0, |z| < 1. We obtain the coefficient inequality, coefficient estimate, distortion theorem, a convolution result, extreme points and integral representation for functions in the class TS p(α).
متن کاملCoefficient estimates for a subclass of analytic and bi-univalent functions
In this paper, we introduce and investigate a subclass of analytic and bi-univalent functions in the open unit disk. Upper bounds for the second and third coefficients of functions in this subclass are founded. Our results, which are presented in this paper, generalize and improve those in related works of several earlier authors.
متن کاملCoefficients of Inverse Functions in a Nested Class of Starlike Functions of Positive Order
In the present paper we find the estimates on the n coefficients in the Maclaurin’s series expansion of the inverse of functions in the class Sδ(α), (0 ≤ δ < ∞, 0 ≤ α < 1), consisting of analytic functions f(z) = z + ∑∞ n=2 anz n in the open unit disc and satisfying ∑∞ n=2 n δ ( n−α 1−α ) |an| ≤ 1. For each n these estimates are sharp when α is close to zero or one and δ is close to zero. Furth...
