| Abstract | ||||
| By using the q-difference Operator we investigate some properties of certain subclasses of harmonic functions defined by using the quantum calculus. We obtain the coefficient estimates and partial sums inequalities of these subclasses.

We obtain the coefficient estimates and partial sums inequalities of these subclasses.
