Sharp bounds for are derived for certain classes and
of meromorphic functions defined on the punctured open unit disk for which and , respectively, lie in a region starlike with respect to 1 and symmetric with
respect to the real axis. Also, certain applications of the main results for a
class of functions defined through Ruscheweyh derivatives are obtained.
