A Tribute to Michael Atiyah, an Inspiration and a Friend. By Alain Connes and Joseph KouneiherSir Michael Atiyah was considered one of the world’s foremost mathematicians. He is best known for his work in
algebraic topology and the codevelopment of a branch of
mathematics called topological 𝐾-theory, together with
the Atiyah–Singer index theorem, for which he received
the Fields Medal (1966). He also received the Abel Prize
(2004) along with Isadore M. Singer for their discovery and
