On certain classes of p-Valent functions by using complex-order and differential subordination. [PDF]
The aim of the present paper is to study the p-valent analytic functions in the unit disk and satisfy the differential subordinations z(Ip)r, ?(f(z))(j+1)/(p - j)(?p(r, ?)f(z))(j) < (a + (aB + (A- B)ß)z)/a(1 + Bz), where ?p(r, ?) is an operator defined ...

Generalizations of p-valent functions via the hadamard product
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 ...

ON CERTAIN MEROMORPHIC P-VALENT FUNCTIONS
Summary: A certain differential operator \(D^n\) is introduced for functions of the form \(f(z)={1\over z^p}+\sum^\infty_{k=0}a_kz^k\) which are analytic in \(E^*=\{z ...
