Convolution and differential subordination for multivalent functions.
Coefficient bounds for meromorphic starlike and convex functions.
A third-order differential equation and starlikeness of a double integral operator.
Differential subordination and convexity criteria of integral operators
A significant connection between certain second-order differential subordination and subordination of f′(z) is obtained. This fundamental result is next applied to investigate the convexity of analytic functions defined in the open unit disk. As a consequence, criteria for convexity of functions defined by integral operators are determined. Connections are also made to earlier known results.
