Guoliang Yu

Yu's research interests include noncommutative geometry, higher index theory of elliptic operators, K-theory, and geometric group theory. He is best known for his fundamental contributions to the Novikov conjecture on homotopy invariance of higher signatures, the Baum–Connes conjecture on K-theory of group C*-algebras, and the stable Borel conjecture on rigidity of manifolds. In his work on the Novikov conjecture, he developed controlled operator K-theory. In the mathematical literature, several concepts are named after him, including Yu's property A and Yu's localization algebra.
Yu has delivered invited addresses at the American Mathematical Society meeting in 1999, and at the International Congress of Mathematicians in Madrid in 2006. He was a plenary speaker at the Topology Festival in 2002 and the Geometry Festival in 2007. He is an editor of the Journal of Noncommutative Geometry, the Annals of K-Theory, the Journal of Topology and Analysis, and the Kyoto Journal of Mathematics. Provided by Wikipedia
