An operator model in the annulus
Glenier Bello, Dmitry Yakubovich
For an invertible linear operator on a Hilbert space , put \[ α(T^*,T) := -T^{*2}T^2 + (1+r^2) T^* T - r^2 I, \] where stands for the identity operator on and $r\in…
Lorentz spaces and embeddings induced by almost greedy bases in superreflexive Banach spaces
José L. Ansorena, Glenier Bello, Przemysław Wojtaszczyk
The aim of this paper is to show that almost greedy bases induce tighter embeddings in superreflexive Banach spaces than in general Banach spaces. More specifically, we show that a…
Toward an optimal theory of integration for quasi-Banach-space-valued functions
José L. Ansorena, Glenier Bello
We present a new approach to define a suitable integral for functions with values in quasi-Banach spaces. The integrals of Bochner and Riemann have deficiencies in the non-locally…
Functional models up to similarity and -contractions
Luciano Abadias, Glenier Bello, Dmitry Yakubovich
We study the generalization of -isometries and -contractions (for positive integers ) to what we call -isometries and -contractions for positive real numbers . We…
