BI- UNIVALENT PROBLEM FOR CERTAIN GENERALIZED CLASS OF ANALYTIC FUNCTIONS INVOLVING Q-INTEGRAL OPERATOR ASSOCIATED WITH NEPHROID DOMAIN.

Abstract

The authors in this article study a new subclass of bi-univalent

functions involving q-integral operator associated with nephroid domain by

using the concept of subordination and bi-linear fractional principles.We further

employed our investigation to determine new coe cient bounds and subsequently

obtain the Fekete-Szego inequalities for functions belonging to the

aforementioned subclass were obtained.
