On certain classes of fractional p-valent analytic functions
Известия Иркутского государственного университета: Серия "Математика", 2015 The theory of analytic functions and more specific p-valent functions, is one of the most fascinating topics in one complex variable. There are many remarkable theorems dealing with extremal problems for a class of p-valent functions on the unit disk U ...

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.

On certain subclasses of p-valent functions [PDF]
Journal of Classical Analysis, 2014 Summary: This paper gives some inclusion relationships of certain class of \(p\)-valent functions which are defined by using the new linear operator \(\mathfrak{Re}^{\alpha, \gamma}_{\beta,p}\). Further, a property preserving integrals is considered.

On the starlikeness of p-valent functions
TURKISH JOURNAL OF MATHEMATICS, 2019 Summary: For an analytic function in open unit disk \(\mathbb{D}\), we consider the \(p\)-valent analogue of the Noshiro-Warschawski univalence condition. We apply the Fejér-Riesz inequality to establish some sufficient conditions for functions to be \(p\)-valent or to be a Bazilevič function or to be in some other classes.

The Relationships Between p−valent Functions and Univalent Functions
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015 In this paper, we obtain some sufficient conditions for general p−valent integral operators to be the p−th power of a univalent functions in the open unit disk.

Generalizations of p-valent functions via the hadamard product
International Journal of Mathematics and Mathematical Sciences, 1982 The classes of univalent prestarlike functions Rα, α≥−1, of Ruscheweyh [1] and a certain generalization of Rα were studied recently by Al-Amiri [2]. The author studies, among other things, the classes of p-valent functions R(α+p−1) where p is a positive ...
