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

open access: yesAxioms, 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.

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

open access: yesTikrit 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 ...

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.

On certain classes of p-Valent functions by using complex-order and differential subordination. [PDF]

open access: yes, 2010
The aim of the present paper is to study the p-valent analytic functions in the unit disk and satisfy the differential subordinations z(Ip)r, ?(f(z))(j+1)/(p - j)(?p(r, ?)f(z))(j) < (a + (aB + (A- B)ß)z)/a(1 + Bz), where ?p(r, ?) is an operator defined ...
