摘要
We show that if N is a nest with no isolated atoms of finite multiplicity, then the invertibles in T(N) are connected. The key technical ingredient is that in such nest algebras, every operator with zero atomic diagonal part factors through the non-atomic part of N. In particular, these results apply for the Cantor nest.
