Fredholmness and compactness of truncated Toeplitz and Hankel operators

R. V. Bessonov

We prove the spectral mapping theorem $σ_{e} (A_{ϕ}) = ϕ (σ_{e} (A_{z}))$ for the Fredholm spectrum of a truncated Toeplitz operator $A_{ϕ}$ with symbol $ϕ$ in the Sarason algebra $C + H^{\infty}$ …

Duality theorems for coinvariant subspaces of $H^{1}$

R. V. Bessonov

Let $θ$ be an inner function satisfying the connected level set condition of B. Cohn, and let $K_{θ}^{1}$ be the shift-coinvariant subspace of the Hardy space $H^{1}$ generated by $θ$ .…
