The objective of this paper is to obtain an upper bound to the second Hankel determinant  for the function f and its inverse belonging to the class of pre-starlike functions of order alpha (0 = alpha = 1), using Toeplitz determinants.

The objective of this paper is to obtain best possible upper bound to the third Hankel determinant for the pre-starlike functions of order a (0 = a < 1), using Toeplitz determinants.

The aim of the present paper is to investigate some characterization for generalized Bessel functions of the first kind is to be a subclass of analytic functions. Furthermore, we studied coefficient estimates, radius of starlikeness, convexity, close - to... see more

The purpose of the present paper is to establish some results involving coefficient conditions, distortion bounds, extreme points, convolution, and convex combinations for a new class of harmonic univalent functions in the open unit disc \ associated with... see more

In the present investigation, we find estimates on the coefficients |a2| and |a3| for functions in the function class S_{S}(?,h). The results presented in this paper improve or generalize the recent work of Magesh and Yamini.

In the present paper, the author defines a class of analytic generalized Sakaguchi type spiral-like functions on the open unit disk U and obtain certain sufficient condition for functions to be in this class. Several corollaries and consequences of the ma... see more
