The degree of similarity of an operator algebra Academic Article uri icon

abstract

  • Let H be a Hilbert space and let A B(H) be a unital closed subalgebra (not necessarily self adjoint). We introduce the "degree of similarity" of A, denoted by d(A), which is a non-negative integer or possibly , and we study its significance in connection with the notions of amenability for groups and operator algebras.
