## A solution to the invariant subspace problem on the space $$\ell _ 1$$.(English)Zbl 0574.47006

The paper is an addendum to the author’s earlier paper [ibid. 16, 337-401 (1984; Zbl 0566.47003)]. In this note he indicates modifications which yield an operator on the space $$\ell_ 1$$ with no proper invariant subspaces. The problem for operators on Hilbert space or reflexive Banach spaces remains open.
