A special volume of Documenta Mathematica was published in honor of his 50th birthday, together with research papers written by leading number theorists and former students it contains Kato's song on Prime Numbers.[4]

Research and contributions

edit

Kato has researched and contributed to various areas in number theory and geometry, some of which include: the "Galois theory of fields, Iwasawa theory, p-adic cohomology, L-functions, K-theory and Hodge theory." He started the use of logarithmic structure to redefine Hodge structure as well.[2]

Awards and honors

edit

In 2005, Kato received the Imperial Prize of the Japan Academy for "Research on Arithmetic Geometry".[5]
