A Study of Some Families of Multivalent <i>q</i>-Starlike Functions Involving Higher-Order <i>q</i>-Derivatives

In the present investigation, by using certain higher-order <i>q</i>-derivatives, the authors introduce and investigate several new subclasses of the family of multivalent <i>q</i>-starlike functions in the open unit disk. For each of these newly-defined function classes, sev...
