On a certain class of p-valent functions with negative coefficients
Amsheri, S. M.; Abouthfeerah, N. A. (ELMERGIB UNIVERSITY, 2022-01)In this paper we introduce a new class of p-valent starlike functions with negative coefficients defined by fractional derivative operator. We obtain coefficient bounds, distortion inequalities, Hadamard product, linear ... -
On Coefficient Bounds for Certain Classes of Analytic Functions
Amsheri, S. M. (ELMERGIB UNIVERSITY, 2021-07)In the present paper we obtain Fekete-Szegö inequalities and sharp bounds for certain classes of analytic and p-valent functions in the open unit disk involving certain fractional derivative operator.
