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 ...
Mathematician Per Enflo, who solved a huge chunk of the 'invariant subspaces problem' decades ago, may have just finished his work. When you purchase through links on our site, we may earn an ...

The study of shift-invariant systems and abelian groups underpins several modern advances in harmonic analysis, signal processing and pure mathematics. At its core, this area explores how translation ...
Recent advances in the domain have further refined the understanding of Aluthge transforms. Notably, investigations into the generalized spherical Aluthge transform have determined its spectral ...
In this paper, a sufficient condition for the existence of hyperinvariant subspace of compact perturbations of multiplication operators on some Banach spaces is presented. An interpretation of this ...
