Abstract: DOI: 10.24193/subbmath.2022.3.01 Published Online: 2022-09-20 Published Print: 2022-09-30 pp. 465-473 VIEW PDF FULL PDF In this present investigation, we introduce a certain subclass Sq(λ;γ; h) of analytic functions which is specify in terms of a quasi-subordination. Sharp bounds of the Fekete-Szegő coefficient for functions belonging to the class Sq(λ;γ; h) are obtained. The results presented give improved versions for the classes involving the quasi-subordination and majorization. Mathematics Subject Classification (2010) : 30C45. Keywords: Univalent functions, subordination, quasi-subordination, Fekete-Szegő coefficients. |
