Generalizations of p-valent functions via the hadamard product
International Journal of Mathematics and Mathematical Sciences, 1982 The classes of univalent prestarlike functions Rα, α≥−1, of Ruscheweyh [1] and a certain generalization of Rα were studied recently by Al-Amiri [2]. The author studies, among other things, the classes of p-valent functions R(α+p−1) where p is a positive ...
