A universal approximation theorem and its applications to vector lattice theory

Eugene Bilokopytov, Foivos Xanthos

A classical result in approximation theory states that for any continuous function $ φ: \mathbb{R} \to \mathbb{R} $, the set \( \operatorname{span}\{φ\circ g : g \in \operatornam…

Pervasiveness of $L^{r} (E, F)$ in $L^{r} (E, F^{δ})$

Quinn Kiervin Starkey, Foivos Xanthos

Let $E, F$ be Archimedean Riesz spaces, and let $F^{δ}$ denote an order completion of $F$ . In this note, we provide necessary conditions under which the space of regular operators $\…
