Norming C*-Algebras by C*-Subalgebras Academic Article uri icon


  • We introduce and investigate the notion of a norming C*-subalgebra of C*-algebra. We characterize when von Neumann algebras norm B(H), and construct various examples of abelian and hyperfinite norming subalgebras. We then apply these results to von Neumann algebra cohomology theory and the bounded projection problem for von Neumann algebras. © 2000 Academic Press.
