Corona problem with data in ideal spaces of sequences (1507.03798v2)

Abstract: Let $E$ be a Banach lattice on $\mathbb Z$ having order continuous norm. We show that for any function $f = {f_j}{j \in \mathbb Z}$ from the Hardy space $H\infty (E)$ such that $\delta \leqslant |f (z)|E \leqslant 1$ for all $z$ from the unit disk $\mathbb D$ there exists some solution $g = {g_j}{j \in \mathbb Z} \in H_\infty (E')$, $|g|{H\infty (E')} \leqslant C_\delta$ of the B\'ezout equation $\sum_j f_j g_j = 1$, also known as the vector-valued corona problem with data in $H_\infty (E)$.
