Özet
We study a subclass of bi-starlike functions and obtain, for the first time, the initial seven Taylor- Maclaurin coefficient estimates |a(2)|, |a(3)|, . . . , |a(7)| for functions from a subclass of the function class sigma. Some new or known consequences of the accumulated results are also pointed out.
