Simple sufficient conditions for starlikeness and convexity for meromorphic functions
Open Mathematics, 2016 In this paper we investigate some extensions of sufficient conditions for meromorphic multivalent functions in the open unit disk to be meromorphic multivalent starlike and convex of order α.

Subordination results for a class of analytic functions
Moroccan Journal of Pure and Applied Analysis, 2021 In this paper, we derive several subordination results and integral means result for certain class of analytic functions with complex order defined by means of q-differential operator. Some interesting corollaries and consequences of our results are also

Convolutions of harmonic right half-plane mappings
Open Mathematics, 2016 We first prove that the convolution of a normalized right half-plane mapping with another subclass of normalized right half-plane mappings with the dilatation −z(a+z)/(1+az)$ - z(a + z)/(1 + az)$ is CHD (convex in the horizontal direction) provided a=1$a

On a class of analytic functions generated by fractional integral operator
Concrete Operators, 2017 In this note, we improve the idea of the Tsallis entropy in a complex domain. This improvement is contingent on the fractional operator in a complex domain (type Alexander).

Starlike and convexity properties of q-Bessel-Struve functions
Demonstratio Mathematica, 2022 This paper introduces three different normalization associated with the second and third q-Bessel-Struve functions. We use Hadamard factorizations to determine the radii of starlike and convexity of these functions.

On univalent functions defined by a generalized Sălăgean operator
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 27, Page 1429-1436, 2004., 2004 We introduce a class of univalent functions Rn(λ, α) defined by a new differential operator Dnf(z), n ∈ ℕ0 = {0, 1, 2, …}, where D0f(z) = f(z), D1f(z) = (1 − λ)f(z) + λzf′(z) = Dλf(z), λ ≥ 0, and Dnf(z) = Dλ(Dn−1f(z)). Inclusion relations, extreme points of Rn(λ, α), some convolution properties of functions belonging to Rn(λ, α), and other results are ...

The class of functions spirallike with respect to a boundary point
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 40, Page 2133-2143, 2004., 2004 The aim of this paper is to present an analytic characterization of the class of functions δ‐spirallike with respect to a boundary point. The method of proof is based on Julia′s lemma.

[Retracted] Partial sums of functions of bounded turning
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 1, Page 45-47, 2004., 2004 We determine conditions under which the partial sums of the Libera integral operator of functions of bounded turning are also of bounded turning.
