SeoudyDepartment of Mathematics, Faculty of Science, Fayoum University, Fayoum 63514, Egypt.Journal Article20121024In this paper we obtain coefficient characterization, extreme points and <br />distortion bounds for the classes of harmonic $p-$valent functions <br />defined by certain modified operator. Some of our results improve <br />and generalize previously known results.http://bims.iranjournals.ir/article_584_80f49ae4626a72fd21eb056231c7bca7.pdf
