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

arXiv:1506.02202

Abstract

Let be a proper ideal of $H^{\infty}(\D)$. We prove the corona theorem for infinitely many generators on the algebra 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.
