In , Sakaguchi introduce the class of functions starlike with respect
to symmetric points. We extend this class. For , let be the
class of normalised analytic functions defined in the open unit disc such
that , for some . In this paper, we introduce 2
other similar classes , as well as give sharp results for the real
part of some function for , and The behaviour of certain
integral operators are also considered.
