## Invariant subspaces and Deddens algebras

My paper entitled `Invariant subspaces and Deddens algebras’ has been accepted for publication in Expositiones Mathematicae. Here is the abstract

It is shown that if the Deddens algebra $\mathcal D_T$
associated with a quasinilpotent operator $T$
on a complex Banach space is closed and localizing then $T$
has a nontrivial closed hyperinvariant subspace.
