Coefficient bounds for \(p\)-valent functions

Open Journal of Mathematical Analysis, 2023
This present paper introduces two new subclasses of p-valent functions. The coefficient bounds and Fekete-Szego inequalities for the functions in these classes are also obtained.

Coefficient Bounds for q-Noshiro Starlike Functions in Conic Region

Journal of Function Spaces
We present and examine a new family of analytic functions that can be described by a q-Ruscheweyh differential operator. We discuss several novel results, including coefficient inequalities and other noteworthy properties such as partial sums and radii ...

Sufficiency Conditions for a Class of Convex Functions Connected with Tangent Functions Associated with the Combination of Babalola Operators and Binomial Series

Mathematics
In this paper, we create a new subclass of convex functions given with tangent functions applying the combination of Babalola operators and Binomial series.

Coefficients of functions with bounded boundary rotation [PDF]

Proceedings of the American Mathematical Society, 1971
For k ≧ 2 k \geqq 2 denote by V k {V_k} the class of normalized functions analytic in the unit disc which have boundary rotation at most k π k\pi . For fixed n ≦ ( k + 6 )

Coefficient Bounds and Fekete-Szego inequalities for A class of Bazilevic type functions associated with new differential operator

Journal of Kufa for Mathematics and Computer, 2019
We generalized a class of Bazilevic type functions as defined in the open unit disk associated with a differential operator satisfying some subordination conditions. As well as, we obtained coefficient bounds and Fekete Szego bounds for functions in this

Sharp Coefficient Bounds for Starlike Functions Associated with Cosine Function

Axioms
Let Scos* denote the class of normalized analytic functions f in the open unit disk D satisfying the subordination zf′(z)f(z)≺cosz. In the first result of this article, we find the sharp upper bounds for the initial coefficients a3, a4 and a5 and the ...

Coefficient Bounds for Certain Subclasses of m-Fold Symmetric Biunivalent Functions

Journal of Mathematics, 2015
We consider two new subclasses SΣmα,λ and SΣmβ,λ of Σm consisting of analytic and m-fold symmetric biunivalent functions in the open unit disk U. Furthermore, we establish bounds for the coefficients for these subclasses and several related classes are ...

Coefficient bounds for q-convex functions related to q-Bernoulli numbers

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
The main objective of this paper is to present and investigate a subclass 𝒞(b, q) of q-convex functions in the unit disk that is defined by the q-Bernoulli numbers.
