Abstract: We give some results of various kinds concerning $\lambda$-spirallike functions of complex order and $\lambda$-Robertson functions of complex order in the unit disc $U=\{z:|z|<1\}$. They represent extensions and generalizations of many previous results. We mainly used the subordination method.

Keywords: $\lambda$-Spirallike, $\lambda$-Robertson functions, subordination

Classification (MSC2000): 30C45
