##### Geometric Properties and Neighborhood for Certain Subclasses of Multivalent Functions

**Authors:**
Hesam Mahzoon

**Abstract:**

By using the two existing operators, we have defined an operator, which is an extension for them. In this paper, first the operator is introduced. Then, using this operator, the subclasses of multivalent functions are defined. These subclasses of multivalent functions are utilized in order to obtain coefficient inequalities, extreme points, and integral means inequalities for functions belonging to these classes.

**Keywords:**
Coefficient inequalities,
extreme points,
integral means,
multivalent functions,
Al-Oboudi operator,
and Sãlãgean operator.
