چکیده

Let K = ( k j ) be an increasing sequence of integers, 0 , and E a class analytic in the disk D z : < 1 functions f such that for some p ∈ ℕ all derivatives are middle -valent . It is proved every function entire if only lim → ∞ ln - ∑ s +

Certain Subclasses of Analytic p-valent Functions with Negative Coefficients

Abstract. The object of the present paper is to study certain subclasses J∗ p (a, b, σ) and Cp(a, b, σ) of analytic p-valent functions, and obtain coefficient bounds and distortion properties for functions belonging to these subclasses. Further results include distortion inequalities and radii of close-toconvexity, starlikeness and convexity for these classes of functions.

Some Properties of a Class of p-valent Analytic Functions Associated with Convolution

In this paper, we define a class R h p,m,β associated with convolution of p-valent analytic functions. Some properties in the form of coefficient inequality, growth and distortion bounds, sufficient conditions with the help of various lemmas, integral means inequality for convolution of two functions and a set of class preserving integral operators of functions belonging to this class are studi...

Applications of convolution and‎ ‎subordination to certain $p$-valent functions

In this paper we considered some new classes of multivalent functions by using Aouf-Silverman-Srivastava operator and derived some important results using convolution and subordination technique. This new class is an extension of a class which introduced before.
