Research ArticleOpen accessA Certain Subclass of Meromorphically Multivalent Analytic Functions with Negative CoefficientsM.Z. Ahmad, Hiba F. Al-Janaby, Rabha W. IbrahimThe paper aims to introduce a certain subclass S*g(A,B,α,p,j) of the class Σ*(p) of meromorphically multivalent functions with negative coefficients, defined by using the definitions of Hadamard product and subordination for two functions belong to the class Σ*(p). We first investigate the geometric characterization property, giving the coefficient estimates for functions in the class S*g(A,B,α,p,j). We also obtain the distortion … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 2 Oct 2015 · 6,349 accessesView PDFCite
