Further characterization theorems involving the Hadamard (or convolution) are also considered.entechnical reports (mathematics and statistics)Some characterization theorems for starlike and convex functions involving a certain fractional integral operatorTechnical ReportDepartment of MathematicsDepartment of Mathematics and Statistics
