By making use of a familiar analogue of the Ruscheweyh derivative as well a
s of the principle of subordination between two analytic functions, the aut
hors introduce and study rather systematically a certain family of meromorp
hically multivalent functions in the open unit disk
U := {z : z is an element of C and 1\z\ < 1}.
Several inclusion properties of this family are associated with an integral
operator of the Bernardi-Libera-Livingston type. (C) 1999 Elsevier Science
