By making use of a familiar analogue of the generalized hypergeometric function, we introduce and investigate some inclusion properties of certain class of meromorphically p-valent starlike functions of order $\lambda \ $ and certain class of meromorphically p-valent quasi-convex functions of order $\lambda $.

Abstract:
A function that is holomorphic in a set E, in the complex plane, is called p-valent in E if, for every complex number, w, the equation f (z) = w has, at most, p roots in E. In this paper, we established some sufficient conditions for holomorphic functions in the unit disk |z| < 1 to be at most p-valent in the unit disk or p-valent or p-valent starlike in the unit disk.

Abstract:
In this paper we introduce and study a new class of analytic and p-valent functions involving higher-order derivatives. For this p-valent function class, we derive several interesting properties including (for example) coefficient inequalities, distortion theorems, extreme points, and the radii of closeto-convexity, starlikeness and convexity. Several applications involving an integral operator are also considered. Finally, we obtain some results for the modified Hadamard product of the functions belonging to the p-valent function class which is introduced here.

Abstract:
The research presented in this paper deals with analytic p-valent functions related to the generalized probability distribution in the open unit disk U. Using the Hadamard product or convolution, function fs(z) is defined as involving an analytic p-valent function and generalized distribution expressed in terms of analytic p-valent functions. Neighborhood properties for functions fs(z) are established. Further, by applying a previously introduced linear transformation to fs(z) and using an extended Libera integral operator, a new generalized Libera-type operator is defined. Moreover, using the

Abstract:
A function f analytic in a domain D ∈ C is called p-valent in D, if for every complex number w, the equation f ( z ) = w has at most p roots in D, so that there exists a complex number w 0 such that the equation f ( z ) = w 0 has exactly p roots in D. The aim of this paper is to establish some sufficient conditions for a function analytic in the unit disc D to be p-valent starlike in D or to be at most p-valent in D . Our results are proved mainly by applying Nunokawa’s lemmas.

In this paper, by using Poisson distribution probability, some characteristics of analytic multivalent q-symmetric starlike and q-symmetric convex functions of order η are examined. Then, by utilizing the Poisson distribution and the concept of the q-analogue Salagean integral operator, the p-valent convergence polynomial was introduced. Furthermore, a number of subclasses of analytic symmetric p-valent functions linked to novel polynomials are also deduced. After that, specific coefficient constraints are determined and symmetric δ,q-neighborhoods for p-valent functions are defined. In relati

Abstract:
This work addresses a new definition of a fractional integral operator that acts on functions which are m-fold-p-valent symmetric in the unit disk. We provide examples of the considered geometric functions of the m-fold-p-valent symmetric type. Also, using the Hadamard product, we prove several results, including the fractional integral operator associated with the well-known Fox-Wright function. Finally, some properties based on the Briot-Bouquet differential subordination are investigated.

Abstract:
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. In this investigation, we define some general classes of p-valent analytic functions defined by the fuzzy subordination and generalizes the various classical results of the multivalent functions. Our main focus is to define fuzzy multivalent functions and discuss some interesting inclusion results and various other useful properties of some subclasses of

En combinant la théorie multibandes k.p avec le formalisme quantique des fonctions de Green hors-équilibre, nous avons étudié et comparé deux types de dispositifs double-grille dopés p: le transistor MOS «conventionnel» et celui dit «sans jonction».
