QUASI-HADAMARD PRODUCT OF MEROMORPHIC UNIVALENT FUNCTIONS AT INFINITY

TANG Huo,DENG Guan-tie,LI Shu-hai

Abstract:

In this paper, we study quasi-Hadamard product problem for certain new subclasses of meromorphic starlike and convex functions in the punctured disk U^*. By using the method of convolution, we derive some results associated with the quasi-Hadamard product of functions belonging to these subclasses, which generalizes some known results.

Key words: analytic functions meromorphic starlike convex quasi-Hadamard product
