Abstract
We prove a double commutant theorem for separable subalgebras of a wide class
of corona C*algebras, largely resolving a problem posed by Pedersen. Double
commutant theorems originated with von Neumann, whose seminal result evolved
into an entire field now called von Neumann algebra theory. Voiculescu later proved
a C*algebraic double commutant theorem for subalgebras of the Calkin algebra.
We prove a similar result for subalgebras of a much more general class of socalled
corona C*algebras.
