报告人简介:

        李叶舟 北京邮电大学教授,博士生导师, 2001年毕业于中国科学院数学与系统科学研究院数学研究所,获基础数学理学博士学位。主要从事解析函数和亚纯函数的增长性、振荡理论和迭代性质,特别微分差分方程亚纯解的解析性质和动力学现象的研究。主持国家自然科学基金4项。曾获北京邮电大学教学名师奖,北京市教学成果奖。


摘      要:

        The aim of this take is to consider the meromorphic solutions $f$ of a class of nonlinear higher order delay differential equations concerning total derivative in $\mathbb{C}^{m}$, and some value distribution properties of $f$ are obtained under more general growth conditions. Furthermore, we show such solutions $f$ are uniquely determined by their poles and two distinct small functions counting multiplicities,

which can be seen as the improvement and extension of previous results.
