Initial seven coefficient estimates for a subclass of bi-starlike functions
UDC 517.5 In the present article, a subclass of bi-starlike functions is studied and initial seven Taylor–Maclaurin coefficient estimates $|a_{2}|, |a_{3}|, \ldots , |a_{7}|$ for functions in the subclass of the function class $ \Sigma $ are obtained for the first time in the literature.

In the present article, a subclass of bi-starlike functions is studied and initial seven Taylor–Maclaurin coefficient estimates $|a_{2}|, |a_{3}|, \ldots , |a_{7}|$ for functions in the subclass of the function class $ \Sigma $ are obtained for the first time in the literature. Few new or known consequences of the results are also pointed out. |
