A Subclass of Harmonic Functions Related to a Convolution Operator
Journal of Function Spaces, 2016 We introduce a new subclass of harmonic functions by using a certain linear operator. For this class we derive coefficient bounds, extreme points, and inclusion results and also show that this class is closed under an integral operator.

Univalent Functions Formulated by the Salagean-Difference Operator
International Journal of Analysis and Applications, 2019 We present a class of univalent functions Tm(κ, α) formulated by a new differential-difference operator in the open unit disk. The operator is a generalization of the well known Salagean’s differential operator.
