| Abstract | ||
| In this paper, we have introduced two subclasses AR(λ,k,p,ζ,δ) and AC(λ,k,p,ζ,δ) of meromorphically p-valent functions with positive and negative coefficients, defined by differential operator in the punctured unit disk U^*= {z:z∈ C; 0 Keywords Meromorphic Functions --- p-valent --- Differential Operator --- Hadamard Product (Convolution). | ||
