In this paper, we obtain coefficient inequalities for certain subclass of meromorphic univalent function with fixed second coefficient defined by Ruscheweyh derivative. Also we have shown that this subclass is closed under arithmetic mean and convex linear combinations. Lastly we have obtained the radius of convexity. [ABSTRACT FROM AUTHOR]

In this paper, the class ∑λ (α, β &#947,;) of univalent meromorphic functions de- fined by Ruscheweyh derivative in the punctured unit disk U* is introduced. We study some results concerning the partial sums of meromorphic univalent starlike functions and meromorphic univalent convex functions. [ABSTRACT FROM AUTHOR]

In this paper we investigate a family of linear operator defined on the space of p-valent meromorphic functions. By making use of this linear operator, we introduce and investigate several new subclasses of p-valent starlike, p-valent convex, p-valent close-to-convex and p-valent quasi-convex meromorphic functions. Also we establish some inclusion relationships associated with the aforementioned linear operator. Some interesting integral-preserving properties are also considered. [ABSTRACT FROM AUTHOR]

In this paper we consider the class M(f,g; α,β,γ,c) of meromorphic univalent functions defined by convolution with positive coefficients and fixed sec-ond coefficients. We obtained coefficient inequalities, distortion theorems, closure theorems, the radii of meromorphic starlikeness, and convexity for functions of this class. [ABSTRACT FROM AUTHOR]

In the present paper, by making use of the differential subordination and superordination results of Miller and Mocanu, certain classes of admissible functions are determined so that subordination as well as superordination implications of functions associated with an integral operator hold. Additionally, differential sandwich-type result is obtained. [ABSTRACT FROM AUTHOR]

Let Q (α) be the class of functions of the form f(z) = a-1⁄z + ∑k=0∞ akzk (a-1 ≠ 0) which are regular in the punctured disc U* = {z:0 < ∣z∣ < 1) and satisfying Re {(Dn+1 f (z))′⁄(Dn f (z)′) - 2} < -α, 0 ≤ α < 1, ∣z∣ < 1, and n ϵ N0 = {0, 1, 2, …}, where Dn f (z) = a-1⁄z + ∑k=2∞ knak-2zk-2. It is proved that Qn+1 (α) ⊂ Qn (α). Since Q0 9α) is the class of meromorphically convex function of order α(0 ≤ α < 1) the members of Qn (α) are meromorfically convex. Further property preserving integrals are considered. [ABSTRACT FROM AUTHOR]
