A New Class of Harmonic Univalent Functions by the Generalized Salagean Operator
收藏 引用
Wuhan University Journal of Natural Sciences 2007年 第6期12卷 965-970页
作者: LI Shuhai LIU Peide School of Mathematics and Statistics Wuhan University Wuhan 430072 Hubei China Department of Mathematics Chifeng University Chifeng024001 Inner Mongolian China
A complex-valued harmonic functions that are univalent and sense preserving in the unit disk U can be written in the form f = h + g^-, where h and g are analytic in U. We define and investigate a new class SHPλ(α... 详细信息
