Masayoshi Nagata yap 永田 雅 宜, February 9, 1927 - August 27, 2008 - Japanese mathematician, specialist on commutative algebra and algebraic geometry In 1958 he presented a count an example of the assertion of the fourteenth problem of Hilbert
Nagata was born in 1927, in 1947 he entered Nagoya University, where he was a student of Tadashi Nakayama. In 1950 he graduated from the University and for some time worked as an assistant and lecturer at Nagoya University, and then moved to Kyoto University , in 1963, having received the post of professor, and remained in this position until his retirement in 19901
Nagata is best known as the author of key counterexamples: an example of a linear algebraic group whose invariant algebra is not one-born negatively solving Hilbert's 14th problem2, an example of a complete en algebraic variety that cannot be embedded in a projective space3, an example of an infinite-dimensional Noetherian ring4 and others Nagata's compactification theorem en states that any algebraic variety can be embedded in a full variety rings of polynomials in three variables that cannot be represented as a composition of “elementary” automorphism such automorphisms are called “wild” In 2003, Shestakov and Umirbaev proved that the example proposed by Nagata is indeed a wild automorphism5
In 1975-1978, Nagata was a member of the Executive Committee of the International Mathematical Union, in 1979-1982 - Vice-President of the Union6 In 1986 awarded the Japanese Academy Award
