He is professor at Kyoto University in Japan. Shishikura became internationally recognized for two of his earliest contributions, both of which solved long-standing open problems. In his Master's thesis, he proved a conjecture of Fatou from 1920 by showing that a rational function of degree d {\displaystyle d\,} has at most 2 d − 2 {\displaystyle 2d-2\,} nonrepelling periodic cycles. He proved that the boundary of the Mandelbrot set has Hausdorff dimension two, confirming a conjecture stated by Mandelbrot and Milnor. For his results, he was awarded the Salem Prize in 1992, and the Iyanaga Spring Prize of the Mathematical Society of Japan in 1995. More recent results of Shishikura include (in joint work with Kisaka) the existence of a transcendental entire function with a doubly connected wandering domain, answering a question of Baker from 1985; (in joint work with Inou) a study of near-parabolic renormalization which is essential in Buff and Chéritat's recent proof of the existence of polynomial Julia sets of positive planar Lebesgue measure. (in joint work with Cheraghi) A proof of the local connectivity of the Mandelbrot set at some infinitely satellite renormalizable points. (in joint work with Yang) A proof of the regularity of the boundaries of the high type Siegel disks of quadratic polynomials. One of the main tools pioneered by Shishikura and used throughout his work is that of quasiconformal surgery. His doctoral students include Weixiao Shen.

He was a…Goro Nishida (西田 吾郎, Nishida Gorō; 18 September 1943, in Osaka – 2 June 2014) was a Japanese mathematician. He was a leading member of the Japanese school of homotopy theory, following in the tradition of Hiroshi Toda. Nishida received his Ph.D. from Kyoto University in 1973, after spending the 1971–72 academic year at the University of Manchester in England. He then became a professor at Kyoto University in 1990. His proof in 1973 of Michael Barratt's conjecture (that positive-degree elements in the stable homotopy ring of spheres are nilpotent) was a major breakthrough: following Frank Adams' solution of the Hopf invariant one problem, it marked the beginning of a new global understanding of algebraic topology. His contributions to the field were celebrated in 2003 at the NishidaFest in Kinosaki, followed by a satellite conference at the Nagoya Institute of Technology; the proceedings were published in Geometry and Topology's monograph series. In 2000 he was the leading organizer for a concentration year at the Japan–US Mathematics Institute at Johns Hopkins University. Nishida's earliest work grew out of the study of infinite loop spaces; his first paper (in 1968, on what came eventually to be known as the Nishida relations) accounts for interactions between Steenrod operations and Kudo–Araki (Dyer–Lashof) operations. Some of his later work concerns a circle of ideas surrounding the Segal conjecture, transfer homomorphisms, and stable splittings of classifying spaces of groups. The ideas in this series of papers have by now grown into a rich subfield of homotopy theory; it continues today in (for example) the theory of p-compact groups.

The field of toric varieties was developed by Demazure, Mumford, Miyake, Oda and others in the 1970s. He is also known for a book on toric varieties: Convex Bodies and Algebraic Geometry: An Introduction to the Theory of Toric Varieties. In 1958 Oda graduated from Tokai High School in Nagoya, Japan, where Shigefumi Mori and Hisasi Morikawa also graduated from. He earned his bachelor's degree from Kyoto University in 1962, and five years later earned a Ph.D. under David Mumford from Harvard University with thesis Abelian varieties over a perfect field and Dieudonné Modules. After completing his Ph.D., Oda was an associate professor at Nagoya University and became a professor at Tohoku University in 1975. He remained at the university for 28 years. He is an emeritus professor at Tohoku University. Oda wrote "Algebraic Geometry, Sendai, 1985" with Hisasi Morikawa, a former professor at Nagoya University. Tadao has belonged to the Kiwanis Club of Sendai since 1999 and was elected to a three-year term as a trustee of Kiwanis International in 2008.
