Goro Nishida, a Japanese mathematician, (born 18 September 1943 in Osaka, died 2 June 2014), was a leading member of the Japanese school of Homotopy theory (following in the tradition of Hiroshi Toda). He received his PhD from Kyoto University in 1973, after spending the 1971-72 academic year at Manchester University in England. 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〔http://msp.warwick.ac.uk/gtm/2007/10/index.xhtml〕 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〔http://www.mathematics.jhu.edu/JAMI9900/〕 at Johns Hopkins University. His earliest work grew out of the study of infinite loopspaces; his first paper (in 1968, on what came eventually to be known as the Nishida relations) accounts for interactions between Steenrod 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. == References == * G.
