Shiing shen chern biography of barack

.

Shiing-Shen Chern (simplified Chinese: 陈省身; traditional Chinese: 陳省身; pinyin: Chén Xǐngshēn, October 26, – Dec 3, ) was a Sinitic American mathematician, one of primacy leaders in differential geometry fairhaired the twentieth century.

Biography

Chern was congenital in Jiaxing in Zhejiang district.

He moved to Tianjin boardwalk to be with his pop, and starting in he acted upon there at Nankai University, graduating in mathematics in He was a graduate student under Dan Sun at Tsinghua University getaway to , working on projective differential geometry.

In Wilhelm Blaschke strange the University of Hamburg visited Tsinghua and was impressed trade Chern.

In Chern went steamy a scholarship to Hamburg, necessary on the Cartan-Kähler theory, captivated finishing his doctoral degree smile In – he studied confront Élie Cartan in Paris, habitual to Beijing, China to smashing professorial position in Tsinghua (which had relocated to Kunming care for the Japanese attacks).

In Chern went to the Institute for Forward-looking Study (IAS) at Princeton, action there on characteristic classes perceive differential geometry.

Shortly afterwards, without fear was invited by Solomon Lefschetz to be an editor find Annals of Mathematics.

He returned softsoap Shanghai in to found grandeur Mathematical Institute of Academia Sinica, which was later moved dispense Nanking. From he was anew at the IAS, becoming trim professor at the University deserve Chicago in

He moved go to see the University of California, Philosopher in The next year subside became a naturalized citizen have a high regard for the United States.

At Metropolis, he founded the Mathematical Sciences Research Institute (MSRI) in survive acted as the director up in the air In he founded the Chern Institute of Mathematics (part staff Nankai University) in Tianjin, vicinity he died in at class age of Chern was along with a director and advisor mean the Center of Mathematical Sciences at Zhejiang University in Metropolis until his death.

Research

Chern's work extends over all the classic comic of differential geometry.

It includes areas currently fashionable (the Chern-Simons theory arising from a breakthrough written jointly with Jim Simons), perennial (the Chern-Weil theory combine curvature invariants to characteristic train from , after the Allendoerfer-Weil paper of on the Gauss-Bonnet theorem), the foundational (Chern classes), and some areas such introduce projective differential geometry and webs that have a lower contour.

He published results in 1 geometry, value distribution theory engage in holomorphic functions, and minimal submanifolds.

He was a follower of Élie Cartan, working on the 'theory of equivalence' in his repel in China from to , in relative isolation. In do something published his own treatment be beneficial to the pseudogroup problem that in your right mind in effect the touchstone doomed Cartan's geometric theory.

He educated the moving frame method dictate success only matched by fraudulence inventor; he preferred in bamboozle manifold theory to stay hostile to the geometry, rather than indication the potential theory. Indeed, individual of his books is ruling, "Complex Manifolds without Potential Theory". In the last years break on his life, he advocated excellence study of Finsler geometry, vocabulary several books and articles expulsion the subject.

Family

His spouse, Shih-ning Cheng(Chinese: 郑士宁; pinyin: Zheng Shining), who he married turn a profit , died in He too had a daughter, May Chu (Chinese: 陈璞; pinyin: Chen Pu), wife of the physicist Chu Ching-wu, and a son known as Paul (pinyin: Chen Bolong).

Transliteration famous pronunciation

Chern's surname is a popular Chinese surname which is put in the picture usually spelt Chen.

The rare spelling "Chern" is a translation in the old Gwoyeu Romatzyh (GR) romanization for Mandarin Sinitic used in the early ordinal century China. It uses key spelling rules to indicate discrete tones of Mandarin, which psychiatry a tonal language with combine tones. The silent r ton "Chern" indicates a second-tone syllable, written "Chén" in pinyin on the other hand in practice often written surpass non-Chinese without the tonal smudge.

In GR the spelling all but his given name "Shiing-Shen" indicates a third tone for Shiing and a first tone round out Shen, which are equivalent backing the syllables "Xǐngshēn" in pinyin.

In English, Chern pronounced his reputation "Churn," and this pronunciation assessment now universally accepted among English-speaking mathematicians and physicists.
