Coefficient inequalities for $q$-starlike functions associated with the Janowski functions
TL;DR: In this paper, the main purpose of the investigation is to find several coefficient inequalities and a sufficient condition for $q$-star-like functions which are associated with the Janowski functions.
Journal ArticleDOI
Hankel and Toeplitz Determinants for a Subclass of q-Starlike Functions Associated with a General Conic Domain
TL;DR: In this paper, the Hankel determinant and Toeplitz matrices for analytic q-star-like functions in the open unit disk U have been obtained for a subclass of normalized analytic and starlike functions.
Journal ArticleDOI
Some General Classes of q-Starlike Functions Associated with the Janowski Functions
TL;DR: This paper first investigates the relationship between various known classes of q-starlike functions that are associated with the Janowski functions, then introduces and study a new subclass ofq-star like functions that involves the Janowsky functions.
Journal ArticleDOI
Some general families of q-starlike functions associated with the Janowski functions
TL;DR: In this article, a new subclass of q-star-like functions which involves the Janowski functions and is related with the conic domain is introduced and a new set of properties of such functions with negative coefficients are derived.
Journal ArticleDOI
Upper Bound of the Third Hankel Determinant for a Subclass of q-Starlike Functions
TL;DR: The main purpose of this article is to find the upper bound of the third Hankel determinant for a family of q-starlike functions which are associated with the Ruscheweyh-type q-derivative operator.
