- Course Description
- Von Neumann algebras are algebras of bounded linear operators
on Hilbert spaces, closed under the adjoint operation and
suitable topologies. They are noncommutative version of measure
spaces. The study of von Neumann algebras is closely related to
ergodic theory, L2-invariants, and mathematical physics. This
course is an introduction to von Neumann algebras. We shall
discuss von Neumann's double commutant theorem, Kaplansky's
density theorem, comparison of projections, type classification,
normal states, traces, and the hyperfinite II_1 factor.
