Certain subclasses of meromorphically pp-valent functions with positive or negative coefficients
چکیده انگلیسی

Making use a linear operator, we introduce two novel subclasses R(n,p,λ,α)R(n,p,λ,α) and C(n,p,λ,α)C(n,p,λ,α) of meromorphically pp-valent functions with positive and negative coefficients, respectively. The main object of this paper is to investigate the various important properties and characteristics of these subclasses of meromorphically pp-valent functions. We also derive many interesting results for the Hadamard products of functions belonging to the classes R(n,p,λ,α)R(n,p,λ,α) and C(n,p,λ,α)C(n,p,λ,α).
