Where is mathematician Yang Le from?
Yang Le, 1939 1 10 was born in Nantong, Jiangsu province. He is a mathematician and mainly engaged in complex analysis research.

1962 graduated from Peking University, and 1966 graduated from Institute of Mathematics, China Academy of Sciences. 1980 was elected as an academician of China Academy of Sciences. Researcher, Institute of Mathematics and System Science, China Academy of Sciences. He used to be the director of the Institute, the director of the Institute of Mathematics of China Academy of Sciences, and the chairman of the Chinese Mathematical Society.

Yang Le mainly studies the value distribution theory of whole functions and meromorphic functions in function theory. He cooperated with Zhang Guanghou and made many creative achievements in the research of analytic functions. Between 1965 and 1977, they published eight important papers in this field. 1982 published the value distribution theory and its new research (Science Press) separately. The connection between "deficient value" and "singular direction" in the theory of function value distribution discovered by him and Zhang Guanghou completely solved the long-standing problem of singular direction distribution in this ancient branch of mathematics. Their estimation of functional defects is also considered to be the result of universal accuracy. International mathematicians call these achievements "Yang Yi's Zhang Theorem" and "Yang Yi's Zhang Inequality".
