Özet

In this study, we investigate approximation properties and obtain Voronovskaja type results for complex modified Szasz-Mirakjan operators. Also, we estimate the exact orders of approximation in compact disks and prove that the complex modified Szasz-Mirakjan operators attached to an analytic function preserve the univalence, starlikeness, convexity and spirallikeness in the unit disk.
