Abstract: DOI: 10.24193/subbmath.2022.3.02 Published Online: 2022-09-20 Published Print: 2022-09-30 pp. 475-487 VIEW PDF FULL PDF In this paper, two new subclasses of bi-univalent functions related to conic domains are defined by making use of symmetric q-differential operator. The initial bounds for Fekete-Szegő inequality for the functions f in these classes are estimated. Mathematics Subject Classification (2010) : 30C45, 30C50. Keywords: Analytic functions, bi-univalent functions, bi-starlike functions, biconvex functions, conic domain, Fekete-Szegő inequality, q-differential operator, univalent functions. |
