Abstract.The object of the present paper is to
introduce two interesting subclasses
and
of
-valent starlike functions in the open unit disc
and prove various coefficient
inequalities and distortion theorems for functions belonging to
these subclasses. The radii of convexity for functions belonging
to the classes
and
are also determined.
