Integral means inequalities are obtained for the fractional derivatives of order of functions belonging to a unified subclass of prestarlike functions. Relevant connections with various known integral means inequalities are also pointed out.


  • Fractional Derivative
  • Negative Coefficient
  • Relevant Connection
  • Prestarlike Function
  • Unify Subclass
