Abstract: The theory of p-valent functions is an important subject in the geometric function theory. Recently, many researchers have shown great interests in the study of p-valent functions. The aim of this paper is to investigate several results concerning the subordination of multivalent functions in the open unit disc U; which are associated with derivative operator D_(δ,β,ʎ,p)^(k,α) f(z).

Keywords: analytic functions, multivalent functions, differential operator, subordination.
