Conference Paper
Full-text available
All papers published in this volume of IOP Conference Series: Materials Science and Engineering have been peer reviewed through processes administered by the proceedings Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing.
Article
Full-text available
In this paper, we introduced a subclass of spiral – like functions defined by generalized Komotu operator with (R – K )integral operator with positive coefficients in the unit disk U . We obtain some new result of this class.
Article
In this paper, we study a new subclass of univalent analytic functions with positive coefficients in the unit disk; we obtain main result, distortion theorem and some properties of this subclass.
Article
In this paper, we study a new class RM* of p-valent functions with negative coefficient defined by integral operator in the unit disk. We obtain some results of this class.
Article
Full-text available
In the present paper , we have studied a class of univalent functions by applying a ((H – R)) fractional calculus , we obtain distortion theorem , wighted mean , arithmetic mean and some results .
Article
Full-text available
In our paper, we study a class of univalent functions with negative coefficients defined by integral operator in the unit disk U by applications fractional calculus . We obtain some results for this class .
Article
Full-text available
In our paper, we study a class W R (λ, β , α, µ, θ), which consists of analytic and univalent functions with negative coefficients in the open unit disk U = {z ∈ C : |z| < 1} defined by Hadamard product (or convolution) with Rafid -Operator, we obtain coefficient bounds and extreme points for this class. Also distortion theorem using fractional cal...
Article
Full-text available
We study a class of functions which are univalent and analytic in the unit disk. We obtain coefficient estimates, distortion bounds and some other results.
Article
Let f be an analytic starlike univalent function. We have introduce a new subclass of starlike univalent functions defined by an integral operator. We obtain a distortion theorem, an integral representation and a linear combination.
Article
Full-text available
In the present paper, we introduce a new class of univalent function with negative coefficients of complex order, by using fractional differ-integral operators studied recently by authors. Coefficient characterization, growth and distortion, radii of starlikeness and convexity , closure theorems of this class of functions are studied. We also study...
Article
We study a linear operator which is defined by means of the Hadamard product (or convolution) with a generalized hypergeometric function, and investigate its various mapping and inclusion properties involving such subclasses of analytic p-valent functions as (for example) k-uniformly convex p-valent functions and k-starlike p-valent functions. We o...
