Algebras of bounded functions with smooth coanalytic part
In this note, the author states (without proofs) several results which extend (i) Fefferman's theorem on the decomposition of BMO and (ii) the corona theorem for \(H^{\infty}\). The author also states results pertaining to Toeplitz and Hankel operators that act on certain spaces of smooth functions.
