Functional inequalities for several classes of q -starlike and q -convex type analytic and multivalent functions using a generalized Bernardi integral operator

In the article we introduce and investigate several new subclasses of q-starlike and q-convex type analytic and multivalent functions involving a generalized Bernardi integral operator, and establish the Fekete-Szego type functional inequalities for these function classes. Besides, the corresponding bound estimates of the coefficients ap+1 and ap+2 are obtained.
