Graeme Segal

High Quality Content by WIKIPEDIA articles! Graeme B. Segal (born 1942) is a British mathematician, and professor at the University of Oxford. He received his Ph.D. in 1967 from the University of Oxford; his thesis, written under the supervision of Michael Atiyah, was titled Equivariant K-theory. His thesis was in the area of equivariant K-theory and the Atiyah-Segal completion theorem in that subject was a major motivation for the Segal conjecture, which he formulated. He has made many other contributions to homotopy theory in the past four decades, including an approach to infinite loop spaces. He was also a pioneer of elliptic cohomology, which is related to his interest in topological quantum field theory.
