Özet

In this present investigation, with the help of the Sălăgean differential operator and the Hadamard product, we define new subclasses of analytic functions. We investigate sharp upper bounds for these subclasses. The results presented in this paper have been shown to generalize and improve some recent work of Frasin and Darus (Internat J Math Math Sci 24(9): 577–581, 2000).
