Certain Subclasses of Meromorphically q-Starlike Functions Associated with the q-Derivative Operators

  • Published:
Ukrainian Mathematical Journal Aims and scope

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.
