Fekete-Szegö inequality of bi-starlike and bi-convex functions of order $b$ associated with symmetric $q$-derivative in conic domains

R. B. Sharma, K. Rajya Laxmi, N. Magesh

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…
