APPLIED MATHEMATICS LETTERS 2010年 第10期23卷 1147-1151页
作者: Kowalczyk, Joanna Les-Bomba, Edyta Univ Rzeszow Inst Math PL-35310 Rzeszow Poland
We consider a subclass of the class of close-to-convex functions. We show the relationship between our class and the appropriate subordination. Moreover, we give the coefficient estimates and a sufficient condition fo... 详细信息
