Abstract

We study bounded linear regularity of finite sets of closed subspaces in a Hilbert space. In particular, we construct for each natural number \(n \ge 3\), a set of \(n\) closed subspaces of \(\ell^{2}\) which has the bounded linear regularity property, while the bounded linear regularity property does not hold for each one of its nonempty, proper non-singleton subsets. We also establish a related theorem regarding the bounded regularity property in metric spaces. 10.1017/S0004972713000749
