Abstract

Let EE be a Banach lattice on Z\mathbb Z having order continuous norm. We show that for any function f={fj}jZf = \{f_j\}_{j \in \mathbb Z} from the Hardy space H(E)H_\infty (E) such that δf(z)E1\delta \leqslant \|f (z)\|_E \leqslant 1 for all zz from the unit disk D\mathbb D there exists some solution g={gj}jZH(E)g = \{g_j\}_{j \in \mathbb Z} \in H_\infty (E'), gH(E)Cδ\|g\|_{H_\infty (E')} \leqslant C_\delta of the B\'ezout equation jfjgj=1\sum_j f_j g_j = 1, also known as the vector-valued corona problem with data in H(E)H_\infty (E).
