New subfamily of meromorphic multivalent starlike functions in circular domain involving q-differential operator

Muhammed Arif and Bakhtiar Ahmad
From the journal Mathematica Slovaca


The main object of the present paper is to investigate a number of useful properties such as sufficiency criteria, distortion bounds, coefficient estimates, radius of starlikness and radius of convexity for a new subclass of meromorphic multivalent starlike functions, which are defined here by means of a newly defined q-linear differential operator.
