Schatten-class characterization for truncated Hankel operators of one-component inner functions
Let θ\thetaθ be a one-component inner function, let Kθ=H2⊖θH2\mathcal K_\theta=H^2\ominus\theta H^2Kθ=H2⊖θH2, and let Γϕ:Kθ→zKθ‾\Gamma_{\phi}:\mathcal K_\theta\to\overline{z\mathcal K_\theta}Γϕ:Kθ→zKθ be a truncat…
