چکیده
|
Abstract. in this paper, we define and investigate a new class of spirallike harmonic functions defined by a salagean differential operator and we obtain a coefficient inequality for the functions in this class. following, we investigated convolution and obtain the order of convolution consistence for certain spirallike harmonic univalent functions with negative coefficients.
