Class of meromorphic univalent functions with positive coefficients associated with a generalized q -S?l?gean operator

摘要

In this paper, using q ? derivative operator, we define the class Σ q , v ? ( n , α , β , λ ) of meromorphic univalent functions and obtain coefficient estimates, distortion, closure theorems, modified Hadamard products, some radii for functions in this class and family of integral operators. Further, we determine partial sums results.
