Sažetak
An attractive and fairly large class of completely bounded (cb) linear maps on C*-algebras that preserve their ideals is the class of elementary operators, that is, those that can be expressed as a finite sum of two- sided multiplications x↦axb. Motivated by the fact that derivations and automorphisms of C*-algebras are also completely bounded, we consider which derivations and automorphisms of C*-algebras admit the cb-norm approximation by elementary operators.
