Multivalent Functions and Differential Operator Extended by the Quantum Calculus

open access: yesFractal and Fractional, 2022
We used the concept of quantum calculus (Jackson’s calculus) in a recent note to develop an extended class of multivalent functions on the open unit disk. Convexity and star-likeness properties are obtained by establishing conditions for this class.

Commuting analytic functions [PDF]

open access: yesTransactions of the American Mathematical Society, 1984
Let f f and g g (not conformal automorphisms of the unit disk) be analytic mappings of the unit disk into itself. We say f f and g g commute if f ∘ g = g ∘ f f \circ g = g \circ f .

Properties of Functions Involving Struve Function

open access: yesMathematics, 2018
Let f ( z ) = z + ∑ n = 2 ∞ a n z n and g p , b , c ( z ) = z + ∑ n = 2 ∞ ( − c 4 ) n − 1 ( 3 2 ) n − 1 ( k ) n − 1 z n with

On Bounded Analytic Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1950
The objective of this paper is to give an alternative derivation of results on bounded analytic functions recently obtained by Ahlfors [1] and Garabedian [2].1 While it is admitted that the main idea to be used is more in the nature of a lucky guess than of a method, it will be found that the gain in brevity and simplicity of the argument is ...

Fekete-Szegö functional for a class of non-Bazilevic functions related to quasi-subordination

open access: yesDemonstratio Mathematica, 2023
In this article, we study the Fekete-Szegö functional associated with a new class of analytic functions related to the class of bounded turning by using the principle of quasi-subordination.

Necessary and Sufficient Conditions for Normalized Wright Functions to Be in Certain Classes of Analytic Functions

open access: yesMathematics, 2022
In this paper, the function classes SPp(σ,ν) and UCSP(σ,ν) are investigated for the normalized Wright functions. More precisely, several sufficient and necessary conditions are provided so that the aforementioned functions are in these classes ...

Quasiconformal variation of slit domains [PDF]

open access: yes, 2001
We use quasiconformal variations to study Riemann mappings onto variable single slit domains when the slit is the tail of an appropriately smooth Jordan arc.

Estimation of coefficient bounds for a subclass of Sakaguchi kind functions mapped onto various domains

open access: yesConcrete Operators, 2023
In this article, we define a new subclass of analytic functions ℛ(t,δ){\mathcal{ {\mathcal R} }}\left(t,\delta ) in the open unit disk D{\mathbb{D}} associated with the petal-shaped domain.
