蒲保明

蒲保明(1910年8月—1988年2月22日),又名蒲保民,男,四川金堂人,中国数学家。他是最早研究收缩几何学英语systolic geometry的学者之一,1952年证明了实射影平面蒲不等式英语Pu's inequality。随后他主要研究领域为模糊数学。他是四川大学数学系教授,并长期担任系主任。

生平

1925年至1933年,蒲保明先后就读于成都教会学校高琦初级中学和华西协合高级中学。1933年,高中毕业的他考入成都华西协合大学数理系。1937年毕业后,他在成都华美女中担任数学教师兼教导主任。1939年9月,他在中英庚款董事会中获得一个职位,任科学研究助理和科学工作人员,在四川大学数学系和武汉大学数学系作研究工作。蒲保明在李国平的帮助下研究半纯函数,发表了第一篇研究论文。

1941年9月,蒲保明于华西协合大学数学系任讲师,三年后升为副教授。1947年,获得国际红十字会提供的奖学金,赴美国叙拉古斯大学研究生院数学系攻读学位。1950年,蒲保民在美国叙拉古斯大学(即雪城大学)获得博士学位,导师为查尔斯·娄威纳英语Charles Loewner,得到了1952年发表的论文中的结果[1],包含了实射影平面的蒲不等式英语Pu's inequality娄威纳环面不等式英语Loewner's torus inequality[2]。根据叙拉古斯大学大学的记录,数学谱系计划显示他曾使用英文名 Frank[3]。同年9月,任教于美国加州大学贝克莱分校。

1951年2月他回到中国,在华西协合大学数理系任教授。1952年院系大调整后,调到四川大学,培养了一批拓扑学者。在文化大革命其中,他的研究与工作曾被迫停止多年。

1981年,蒲保明成为中华人民共和国第一批基础数学博士导师。他晚年大多数论文都是关于模糊拓扑[2]

1988年2月中旬,蒲保明因感冒入院,24日,突发心肌梗塞去世。

影响

根据 Google Scholar 提供的资料[4]蒲保明的毕业论文从1952年被数学著作引用了87次,是数学上是很高的水准。他与刘应明在模糊拓扑上的工作,仍然经常被模糊数学领域的著作引用[5]
