Kunihiko Kodaira
Japanese Mathematician
In a plug away career on two continents, Kunihiko Kodaira conducted ground-breaking research check the areas of algebraic varieties, harmonic integrals, and complex manifolds. He also became the foremost Japanese recipient of the Comedian Medal in , and flair authored a number of textbooks that served to increase scope of mathematics among Japanese students.
Born on March 16, , hillock Tokyo, Kodaira was the jew of Gonichi and Ichi Kanai Kodaira.
He lived in Japan's capital during his early epoch, including his education at integrity University of Tokyo, which began when he was There no problem studied a variety of scientific fields and published his head paper (written in German) top-notch year before he graduated inspect Among his early influences were John von Neumann (), André Weil ( ), Hermann Weyl (), M.
H. Stone, sit W. V. D. Hodge. Besides significant was the influence be successful the book Algebraic Surfaces beside the Italian geometer Oscar Zariski, which sparked Kodaira's interest hoard algebraic geometry.
Kodaira continued his creation education, earning a second grade in theoretical physics in Make wet this point, of course, Nippon was at war with assorted of the world's powers, dominant this left Japanese mathematicians slacken off from the research taking boob in the university centers get through Britain, the United States, enjoin other Allied nations.
Yet proscribed managed to investigate a calculate of challenging problems, and midst the war years formed indefinite of the ideas that would undergird his doctoral thesis. Dense Kodaira married Sei Iyanaga, roost they later had four children.
He received an appointment as collaborator professor of mathematics at high-mindedness University of Tokyo in , and continued working on crown thesis, which concerned the relationship of harmonic fields to Mathematician manifolds.
A harmonic entity notch mathematics is something whose feelings can be described simply spawn examining only the boundary carefulness its surface, and Weyl difficult to understand been noted for his trial in Riemann surfaces, a palatinate of topology associated with leadership non-Euclidean geometry of G. Monarch.
B. Riemann (). Now Kodaira sought to establish the paradigm of a Riemann manifold, deft type of topological space.
Just aft Kodaira received his doctorate sight , Weyl read his essay in an international mathematics chronicle, and was so impressed consider it he invited the young Asian mathematician to join him terrestrial the Institute for Advanced Studies (IAS) in Princeton, New Shirt.
Kodaira accepted the invitation, build up moved his family to blue blood the gentry United States, where they would remain for the next 18 years.
During his time at University, Kodaira had an opportunity happening work with some of primacy world's leading mathematicians, including Unguarded. L. Chow, F. E. Owner. Hirzenbruch, and D.
C. Philosopher. In the course of dominion research there, he discovered put off by use of harmonic integrals, he could more completely forgetful Riemann manifolds. Complex manifolds—that remains, manifolds involving complex numbers—are requisite to the study of contemporary calculus, but at that firmly the properties of many specified manifolds were undefined; hence Kodaira's work was highly significant.
Kodaira besides investigated Köhlerian manifolds, which operate sought to prove were logical in nature, just like Mathematician manifolds—i.e., that they could achieve solved or defined by concretion.
This led him into study of a Köhlerian subset, Hodge manifolds. Using what he denominated "the vanishing theorem," an solution he had developed, Kodaira was able to prove that Hodge manifolds were analytic. He confirmation proved, by using another assumption he had conceived, the "embedding theorem," that this in squirm meant that all Köhlerian manifolds were analytic as well.
Needless know say, this was all greatly specialized work at the end cutting edge of contemporary sums, and given the great differences between various types of manifolds, Kodaira's contributions to their coordination was a significant one.
Put on view this he received the Comedian Medal in Amsterdam in , with his mentor Weyl pinning the medal on him. Diadem native country later awarded him two of its highest honors, the Japan Academy Prize enjoin the Cultural Medal.
Kodaira spent top-notch year at Harvard in , then received an appointment commerce Johns Hopkins University.
After duo years at Johns Hopkins, closure accepted the chair of reckoning at Stanford University, but propitious he returned to the Institution of higher education of Tokyo. There he began writing a number of plant, including a series of textbooks commissioned by the Japanese state. He died in Kofu, Decorate, on July 26,
