For 𝜆≥ 0 and 0≤ 𝛼< 1< 𝛽, we denote by 𝒦 (𝜆; 𝛼, 𝛽) the class of normalized analytic
functions satisfying the two sided-inequality α< ℜ (zf'(z) f (z)+ λ z 2 f''(z) f (z))< β (z∈ 𝕌) …

By considering a certain univalent function that maps the unit disk 𝕌 onto a strip domain, we
introduce new subclasses of analytic and p-valent functions and determine the coefficient …

The main objective of this investigation is to introduce certain new subclasses of the class
$\Sigma $ of bi-univalent functions by using concept of conic domain. Furthermore, we find …

We aim to estimate coefficient inequalities for some new subfamilies of close-to-convex
functions, which are here, defined by generalized differential operator and Cauchy–Euler …

In this paper, we determine the coefficient bounds for functions in certain subclasses of close-
to-convex functions of complex order, which are introduced here by means of a certain non …

By considering a certain univalent function in the open unit disk U, that maps U onto a strip
domain, we introduce a new class of analytic and close-to-convex functions by means of a …

This paper is emphasizing on the class of analytic function which is univalent in the open
unit disc. The main objective is to study the new subclasses of bi-univalent involving Faber …
