摘要
An interesting criterion was given by Ponnusamy and Singh [S. Pormusamy, V. Singh, Convolution properties of some classes of analytic functions, Internal Report, SPIC Science Foundation, 1990.] for convolution properties of functions in the class P-alpha. In this paper we shall get a new criterion for convolution properties of functions in this class. (c) 2005 Elsevier Ltd. All rights reserved.
