Two weeks ago, a modest-looking paper was uploaded to the arXiv preprint server with the unassuming title “On the invariant subspace problem in Hilbert spaces”. The paper is just 13 pages long and its ...

Let T be an operator with spectrum σ(T) on a Hilbert space. A compact subset E of σ(T) is called a disconnected part of σ(T) if, for some bounded open set A, E is the closure of σ(T) ∩ A and σ(T) - E ...
