ON THE difference COUNTERPART OF BRCK'S CONJECTURE
收藏 引用
Acta Mathematica Scientia 2014年 第3期34卷 653-659页
作者: 陈宗煊 School of Mathematical Sciences South China Normal University
In this article, for a transcendental entire function f(z) of finite order which has a finite Borel exceptional value a, we utilize properties of complex difference equations to prove the difference counterpart of B... 详细信息

Acta Mathematica Sinica,English Series 2016年 第10期32卷 1189-1202页
作者: Ran Ran ZHANG Zong Xuan CHEN Department of Mathematics Guangdong University of Education School of Mathematical Sciences South China Normal University
Let f(z) be a finite order meromorphic function and let c ∈ C / {0} be a constant. If f(z) has a Borel exceptional value α∈ C, it is proved that max{τ(f(z) ), τ( △cf(z) ) } = max{τ(f(z) ), τ... 详细信息

作者: SHON Kwang Ho Department of Mathematics College of Natural SciencesPusan National University
Let f be a transcendental meromorphic function and g(z)=f(z+c1)+f(z+c2)-2f(z) and g2(z)=f(z+c1)·f(z+c2)-f2(z).The exponents of convergence of zeros of differences g(z),g2(z),g(z)/f(z),and g2(z)/f2(z) are estimated ac... 详细信息
