Kazuya Kato

Professor Kazuya Kato is a Professor of Mathematics at the University of Chicago. He is a mathematician in the areas of algebraic number theory and algebraic geometry. He has contributed to the Galois theory of fields, Iwasawa theory, p-adic cohomology, L-functions, K-theory and Hodge theory. The Bloch-Kato conjecture has inspired important developments in number theory. In geometry, he pioneered the use of logarithmic structure to compactify the moduli spaces of Hodge structure; while in arithmetic developed Iwasawa theory in the context of GL2-extensions. Kato is the recipient of the Imperial Prize of the Japan Academy (2005).
