• PARTIAL-SUMS
• CONVEXITY

We establish several general results concerning the partial sums of meromorphically starlike functions defined by means of a certain class of q-derivative (or q-difference) operators. The familiar concept of neighborhood for meromorphic functions is also considered. Moreover, by using a Ruscheweyh-type q-derivative operator, we define and study another new class of functions emerging from the class of normalized meromorphic functions.
