On commutative and non-commutative C*-algebras with the approximate n-th root property

A. Chigogidze, A. Karasev, K. Kawamura +1

We say that a C*-algebra X has the approximate n-th root property (n\geq 2) if for every a\in X with ||a||\leq 1 and every ε>0 there exits b\in X such that ||b||\leq 1 and ||a-b^n|…
