Sharp Second-Order Hankel Determinants Bounds for Alpha-Convex Functions Connected with Modified Sigmoid Functions

open access: yesAxioms
The study of the Hankel determinant generated by the Maclaurin series of holomorphic functions belonging to particular classes of normalized univalent functions is one of the most significant problems in geometric function theory.

Bigradients, Hankel determinants and the Newton-Padé table

open access: yesAequationes Mathematicae, 1978
In [9], Warner introduced generalized bigradients in the study of the Newton-Pade table. In this paper we introduce generalized Hankel determinants and derive, using the framework of Newton-Pade approximation, a relationship between these generalized Hankel determinants and generalized bigradients.

On H3 (1) Hankel determinant for certain subclass of analytic functions

open access: yesExtracta Mathematicae, 2020
The objective of this paper is to obtain an upper bound to Hankel determinant of third order for any function f, when it belongs to certain subclass of analytic functions, defined on the open unit disc in the complex plane.
