Abstract
In this paper, by making use of binomial series, we define a new differential operator of
holomorphic functions in the open unit disk. Also, we introduce and investigate two new
classes containing this new operator associated with differential subordinations and
superordinations. Furthermore, we determine important properties for functions belonging
to these classes.
