Le Yang
Le Yang or Lo Yang, Chinese mathematician (Nantong, Jiangsu Province 10 November 1939 – Beijing 22 October 2023) Introduced the concept of deficient functions and proved its countability With Guanghou Zhang introduced the concept of defects and singularity directions in distribution theory Obtained the precise estimate of total deficiency for any meromorphic function with its derivative With G. Zhang first established the numbers of deficient values and Borel directions of entire and meromorphic functions (1970s) Established new criteria for normality Established relationship between normal families and fixed points as well as that between normal families and different polynomials Established the necessary and sufficient conditions for the distribution of singular directions Found a new kind of singular directions With W.K. Hayman solved a conjecture of Littlewood EPONYMY Le Yang inequality Yang-Zhang theorem (relation between deficit value and singular directions) 1977 Yang-Zhang inequality Yang relation of deficiencies Yang problem in derivative functions with maximal deficiency sum LINKS http://www.hlhl.org.cn/english/showsub.asp?id=251
