On the Fekete-Szegö problem

International Journal of Mathematics and Mathematical Sciences, 2000
Let f(z)=z+a2z2+a3z3+⋯ be an analytic function in the open unit disk. A sharp upper bound is obtained for |a3−μa22| by using the classes of strongly starlike functions of order β and type α when μ≥1.

Univalent and Starlike Properties for Generalized Struve Function

International Journal of Mathematics and Mathematical Sciences, 2016
We derive conditions on the parameters p, b, and c so that the function zwp,b,c(z), where wp,b,c(z) is the normalized form of generalized Struve function, belongs to the class S1⁎(α). Also, some sufficient conditions for the function zwp,b,c(z), to be in

disc. The proof of the local maximum theory for the coefficients of univalent functions by Bombieri [2] and by Garabedian and Schiffer [3] gives strength to the conjecture that these dn exist, but no estimate of their size is available from these papers.

Growth results for a subclass of Bazilevič functions

International Journal of Mathematics and Mathematical Sciences, 1985
For α>0, let B(α) be the class of regular normalized Bazilevič functions defined in the unit disc. Choosing the associated starlike function g(z)≡z gives a proper subclass B1(α) of B(α).

Convex and Starlike Meromorphic Functions [PDF]

Proceedings of the American Mathematical Society, 1980
In this paper we study meromorphic univalent functions with a simple pole at p which map the unit disk onto the exterior of convex sets or the exterior of starlike sets. A question raised by Libera and Livingston concerning the equality of two classes of starlike meromorphic univalent functions is answered. We show that the set of points omitted by the

Coefficient inequalities for certain subclass of starlike function with respect to symmetric points related with q-exponential function

NUML International Journal of Engineering and Computing
The purpose of the present work is to define a class of star-like function with respect to symmetrical points in the domain of exponential functions related to the q-exponential functions.
