Sharp Invertibility in Quotient Algebras of $H^{\infty }$

Alexander Borichev, Artur Nicolau, Myriam Ounaïes +1

We consider inner functions $\hat{I}˜$ with the zero set $\mathcal{Z}(\hat{I}˜)$ such that the quotient algebra $H^{\infty }/\hat{I}˜H^{\infty }$ satisfies the Strong Invertibility Property (SIP), that i…
