Functional Analysis
Noncommutative Geometry is a subfield of Functional Analysis with broad connections to several areas of mathematics. A foundational idea of the field, originating in quantum physics, is the notion that the quantization of a topological space is a noncommutative algebra. The theory of C*algebras provides one way to make this precise. A celebrated theorem of Gelfand and Naimark implies that the category of commutative unital C*algebras is equivalent to the category of compact Hausdorff topological spaces, while every noncommutative C*algebra can be realized as an algebra of operators on Hilbert space. The research of members of this group focuses on diverse topics, such as the study of C*algebras associated to dynamical systems, index theory of elliptic and hypoelliptic operators, groupoids, analytic and topological Ktheory, ConnesHigson Etheory, and Fredholm manifolds.
