Özet
Let A denote the class of functions f which are analytic in the open unit disk U and given by (Formula Presented) In a very recent paper, Alqahtani et al. [AIMS Mathematics 8 (4) (2023), 9385-9399] defined a new subclass S*q α, β (0 ≤ α < 1 < β, 0 < q < 1) consists of functions f ∈ A satisfying the following condition: (Formula Presented) where ∂q f is Jackson’s q-derivative of f. In this study, we introduce a new subclass Sq,g (α, β) of analytic and q-close-to-convex functions satisfying [Formula Presented], where 0 ≤ α < 1 < β and g ∈ S*q (δ, β) with 0 ≤ δ < 1 < β. The main purpose of this paper is to determine some coefficient bounds for functions f ∈ A satisfying the non-homogenous Cauchy-Euler fractional q-differential equation associated with analytic functions belong to the class Sq,g(α, β).
