Bohr Inequality for Odd Analytic Functions [PDF]

open access: yes, 2017
We determine the Bohr radius for the class of odd functions f satisfying $$|f(z)|\le 1$$|f(z)|≤1 for all $$|z|

A new criterion for starlike functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
In this paper we shall get a new criterion for starlikeness, and the hypothesis of this criterion is much weaker than those in [1] and [2].

a*-families of analytic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
Using convolutions, a new family of analytic functions is introduced. This family, called a*-family, serves in certain situations to unify the study of many previously well known classes of analytic functions like multivalent convex, starlike, close-to ...

Geometric Properties of Certain Classes of Analytic Functions Associated with a q-Integral Operator

open access: yesSymmetry, 2019
This article presents certain families of analytic functions regarding q-starlikeness and q-convexity of complex order γ ( γ ∈ C \ 0 ) . This introduced a q-integral operator and certain subclasses of the newly introduced classes are defined by using ...

Nowhere differentiable functions of analytic type on products of finitely connected planar domains [PDF]

open access: yes, 2017
Using Laurent decomposition and Mergelyan’s theorem combined with Baire’s category theorem, we prove generic nowhere differentiability on the distinguished boundary of functions of analytic type on products of planar domains bounded by finitely many ...

Hankel determinant of order three for familiar subsets of analytic functions related with sine function

open access: yes, 2019
In this paper we define and consider some familiar subsets of analytic functions associated with sine functions in the region of unit disk on the complex plane. For these classes our aim is to find the Hankel determinant of order three.

Bohr-type inequalities for bounded analytic functions of Schwarz functions

open access: yesAIMS Mathematics, 2021
In this paper, some new versions of Bohr-type inequalities for bounded analytic functions of Schwarz functions are established. Most of these inequalities are sharp. Some previous inequalities are generalized.

A Hankel matrix acting on spaces of analytic functions [PDF]

open access: yes, 2017
If $\mu $ is a positive Borel measure on the interval $[0, 1)$ we let $\mathcal H_\mu $ be the Hankel matrix $\mathcal H_\mu =(\mu _{n, k})_{n,k\ge 0}$ with entries $\mu _{n, k}=\mu _{n+k}$, where, for $n\,=\,0, 1, 2, \dots $, $\mu_n$ denotes the moment ...
