Inclusion Properties of p-Valent Functions Associated with Borel Distribution Functions

Mathematics, 2023
In this paper, we define a differential operator on an open unit disk Δ by using the novel Borel distribution (BD) operator and means of convolution.

Certain Results on Fuzzy p-Valent Functions Involving the Linear Operator

Mathematics, 2023
The idea of fuzzy differential subordination is a generalisation of the traditional idea of differential subordination that evolved in recent years as a result of incorporating the idea of fuzzy set into the field of geometric function theory.

New sufficient conditions for p-valent functions

Afrika Matematika
Abstract Let $$\mathcal {A}_{p}$$ A p be the class of functions f(z) of the form $$ f(z)=z^{p}+a_{p+1}z^{p+1}+a_{p+2}z^{p+2}+\cdots , (p\in \

Inclusion Properties for Classes of p-Valent Functions

Journal of Function Spaces
Making use of a differential operator, which is defined here by means of the Hadamard product, we introduce classes of p-valent functions and investigate various important inclusion properties and characteristics for these classes.

CERTAIN SUBCLASSES OF MEROMORPHICALLY P-VALENT FUNCTIONS WITH POSITVE OR NEGATIVE COEFICIENTS USING DIFFERENTIAL OPERATOR

Tikrit Journal of Pure Science, 2023
In this paper, we have introduced two subclasses  and  of meromorphically p-valent functions with positive and negative coefficients, defined by differential operator in the punctured unit disk  and obtain some sharp results including coefficient ...

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.

Inclusion and properties neighbourhood for certain p-valent functions associated with complex order and q–p-valent Cătaş operator

Journal of Taibah University for Science, 2020
Here in our paper, we present two new subclasses of multivalent analytic functions and complex order by using q–p-valent Cătaş operator. Also we obtain coefficient estimates and consequent inclusion relationships involving the $N_{i,\delta }^{\mathbf {p}

Subclasses of p-Valent Functions Associated with Linear q-Differential Borel Operator

Mathematics, 2023
The aim of the present paper is to introduce and study some new subclasses of p-valent functions by making use of a linear q-differential Borel operator.We also deduce some properties, such as inclusion relationships of the newly introduced classes and ...

Some New Sufficient Conditions on p-Valency for Certain Analytic Functions

Axioms, 2023
In the present paper, we develop some implications leading to Carathéodory functions in the open disk and provide some new conditions for functions to be p-valent functions. This work also extends the findings of Nunokawa and others.
