Abstract: |
In this paper, the definition of the modified q-Szász-Kantorovich operator in complex spaces is given, referring to the method of Gal S G et al. [10], and the approximation properties of the modified q-Szász-Kantorovich operator in compact disks when q>1 are studied. Voronovskaja results are obtained, and their exact estimates are given, which enrich the approximation properties of the modified q-Szász-Kantorovich operator in complex spaces. |
