Estimates for the Corona Theorem on $H^{\infty}_{\mathbb{I}}(\D)$

Abstract

Let I\mathbb{I} be a proper ideal of H(\D)H^{\infty}(\D). We prove the corona theorem for infinitely many generators on the algebra HIH^{\infty}_{\mathbb{I}} in which the corona theorem for finitely many functions is known to hold. This settles the conjecture of Ryle \cite{ryle1}. We also provide the estimates for corona solutions. Moreover, we prove a generalized Wolff's Ideal Theorem for this sub-algebra.
