Inclusion and argument properties for certain subclasses of meromorphic functions associated with a family of multiplier transformations

[摘要] Making use of a multiplier transformation, which is defined here by means of the Hadamard product (or convolution), the authors introduce some new subclasses of meromorphic functions and investigate their inclusion relationships and argument properties. Some integral-preserving properties in a given sector are also considered. (C) 2004 Elsevier Inc. All rights reserved.
