Coefficient Inequalities for a Subclass of p-Valent Analytic Functions [PDF]

open access: yesThe Scientific World Journal, 2014
The aim of this paper is to study the problem of coefficient bounds for a newly defined subclass of p-valent analytic functions. Many known results appear as special consequences of our work.

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

open access: yesMathematics, 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 ...

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

open access: yesJournal 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}

On certain subclasses of p-valent functions [PDF]

open access: yesJournal 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.
