MEROMORPHIC FUNCTIONS WITH BOUNDED BOUNDARY ROTATION
收藏 引用
Acta Mathematica Scientia 2014年 第2期34卷 466-472页
作者: jacek dziok Faculty of Mathematics and Natural Sciences University of Rzeszów
In this article, we generalize the class of meromorphic functions with bounded boundary rotation and related classes. Characterizations and some properties of these classes of functions are given.

PROPERTIES OF THE CONVOLUTION WITH PRESTARLIKE FUNCTIONS
收藏 引用
Acta Mathematica Scientia 2013年 第6期33卷 1685-1694页
作者: jacek dziok Institute of Mathematics University of Rzeszów
In the paper we investigate convolution properties related to the prestarlike functions and various inclusion relationships between defined classes of functions. Interest-ing applications involving the well-known clas... 详细信息

HARMONIC FUNCTION WITH CORRELATED COEFFICIENTS
收藏 引用
Acta Mathematica Scientia 2019年 第6期39卷 1661-1673页
作者: jacek dziok Faculty of Mathematics and Natural Sciences University of Rzeszów
In the paper we introduce an idea of harmonic functions with correlated coefficients which generalize the ideas of harmonic functions with negative coefficients introduced by Silverman and harmonic functions with vary... 详细信息
