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

Alexander Borichev, Artur Nicolau, Myriam Ounaïes +1

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