中国科学院数学研究所研究员张广厚,是一位年轻的数学家。他和杨乐密切合作,在函数论的研究上,第一次发现了函数值分布论中的两个主要概念——“亏值”和“奇异方向”之间的具体联系。因此,他在国内外数学界享有盛名。解放前,张广厚的家里很穷。张广厚的妈妈是这个大家庭里唯一认得几个字的人。她小时候曾经上过几年私塾。读过一些“之乎者也” Zhang Guanghou, a researcher at the Institute of Mathematics, Chinese Academy of Sciences, is a young mathematician. He worked closely with Yang Le, for the first time in the study of the function theory, to find the concrete connection between the two main concepts of the distribution of functional values ​​- the “deficit” and the “singular direction.” Therefore, he enjoys a good reputation in mathematics circles at home and abroad. Before liberation, Zhang Guanghou’s family was poor. Zhang Guanghou’s mother is the only one in this family to recognize a few words. She had spent a few years as a child’s school.
