%0 Journal Article %T Estimates on initial coefficients of certain subclasses of bi-univalent functions associated with quasi-subordination %A Amol Patil %A Uday Naik %J - %D 2017 %R 10.14419/gjma.v5i1.6959 %X v In the present investigation we introduce some subclasses of the function class ¡Æ of bi-univalent functions defined in the open unit disk U, which are associated with the quasi-subordination. We obtain the estimates on initial coefficients |a2| and |a3| for the functions in these subclasses. Also several related subclasses are considered and connection with some known results are established. %U https://www.sciencepubco.com/index.php/GJMA/article/view/6959
