Najafzadeh, Sh.; Ebadian, A.; Amini, E. Univalent functions with negative coefficients based on order of convolution consistence. (English) Zbl 1344.30013 Int. J. Appl. Math. 28, No. 5, 579-591 (2015). Summary: In this paper we consider the modified Hadamard product or convolution of analytic functions with negative coefficients, combined with an Sălăgean integral operator. We discuss when it is a given class. Following idea of U. Bednarz and J. Sokól we shall determine the order of convolution consistence for certain analytic functions with negative coefficients.
