A certain subclass of analytic functions associated with the quasi-subordination
, 2017 In the present paper we study quasi-subordination under a multivalent function and we consider a certain subclass of (normalized) analytic functions based on quasi-subordination.

On close-to-convex functions satisfying a differential inequality
, 2015 Let C α (β) denote the class of normalized functions f, analytic in the open unit disk E which satisfy the condition… …We claim that our result improves the result of Chichra, P. N. [1].

On the starlikeness of iterative integral operators
, 2016 The main object of the present paper is to investigate starlikeness of certain integral operators, which are defined here by means of iterative in the open disk $\mathbb{D}_R=\{z\in\mathbb{C}:|z|<R\}$ with $R\geq1$.

The order of starlikeness of some classes of strongly starlike functions
, 2018 In this paper we consider the order of strongly starlikeness for functions in Silverman's class Gb and in the generalized Mocanu's class M (α, β1, β2). Some previous results are improved.Mathematics Subject Classification (2010): Primary 30C45; Secondary

Sufficient conditions for Janowski starlike functions
, 2016 Sufficient conditions for confluent (Kummer) hypergeometric function, generalized and normalized Bessel function of the first kind of complex order and integral operator to be subordinate to (1+Az)/(1+Bz) are obtained as applications.

Results on ϕ-like functions involving Hadamard product
In this paper, we derive a differential subordination theorem involving convolution of normalized analytic functions. By selecting different dominants to our main result, we find certain sufficient conditions for ϕ−likeness and parabolic ϕ−likeness of ...

Differential superordination for harmonic complex-valued functions
, 2019 Let Ω and ∆ be any sets in C, and let ϕ(r, s, t; z) : C3 × U → C. Let p be a complex-valued harmonic function in the unit disc U of the form p(z) = p1(z) + p2(z), where p1 and p2 are analytic in U .

Inclusion and distortion properties for certain meromorphically multivalent functions
, 2017 Two new subclasses Hp,k(λA;B) and Qp,k(λA;B) of meromorphically multivalent functions starlike with respect to k-symmetric points are introduced. Distortion bounds and inclusion relations for these subclasses are obtained.Mathematics Subject Classication
