摘要:

研究了某些推广了的q -平移差分方程亚纯解的增长性. 还研究了q -平移差分多项式的值分布, 这些结果可以视为复微分多项式对应结果的q -平移差分模拟. 亦给出了一些例子说明所得结果的精确性.

关键词: q -平移差分方程, q -平移差分多项式, 亚纯解, 零级

Abstract:

In this paper, we investigate the growth of meromorphic solutions of some generalized q-shift difference equations. We also investigate the value distribution of q-shift difference polynomials, which can be viewed as q-shift difference
analogues of corresponding results of differential polynomials. Examples are also given to illustrate the sharpness of our results.

Key words: q-Shift difference equation, q-Shift difference polynomials, Meromorphic solution, Zero-order
