GROWTH OF MEROMORPHIC SOLUTIONS OF SOME ALGEBRAIC DIFFERENTIAL EQUATIONS

In this paper, by means of the normal family theory, we estimate the growth order of meromorphic solutions of some algebraic differential equations and improve the related result of Barsegian et al. [6]. We also give some examples to show that our results occur in some special cases.     

关于整函数超级的进一步结果

运用正规族理论研究了整函数与其高阶导数分担无穷级函数增长级与超级的相关结果.从亚纯函数超级大于零而使球面导数无界的角度出发,然后综合运用Pang-Zaclman引理,数学归纳法和Nevanlinna理论等方法证明了该结果,推广和改进了已有的结果.     

整函数分担多项式的增长性的进一步估计

运用正规族理论将整函数分担多项式增长级的结果进一步精确化估计.同时举例说明的结果是有意义的.     

关于亚纯函数差分多项式的进一步结果

设f为一有穷级为ρ(f)的超越亚纯函数,μ和c作为一非零的常数.设n,m作为一正整数,且设s(z)作为一f的非零小函数.如果n≥m+4或者(m≥n+4),则差分多项式f~n(z)+μf~m(z+c)-s(z)在复平面上有无穷多个零点.
