Recent perspectives on the Invariant Subspace Problem

arXiv:2507.21834

Abstract

We review recent work connected with the invariant subspace problem for operators, in particular new developments in the last 15 years. In particular, we include discussions of almost-invariant subspaces, universal operators, specific classes of operators and new results in the framework of Banach spaces.
