Generalized Volterra operators mapping between Banach spaces of analytic functions

We characterize boundedness and compactness of the classical Volterra operator $T_g \colon H_{v_α}^{\infty} \to H^{\infty}$ induced by a univalent function $g$ for standard weights $v_α$ with $0 \leq α< 1$, partly answering an open problem posed by A. Anderson, M. Jovovic and W. Smith. We also study boundedness, compactness and weak compactness of the generalized Volterra operator $T_g^φ$ mapping between Banach spaces of analytic functions on the unit disc satisfying certain general conditions.

Spectral properties of weighted composition operators on the Bloch and Dirichlet spaces

The spectra of invertible weighted composition operators $uC_φ$ on the Bloch and Dirichlet spaces are studied. In the Bloch case we obtain a complete description of the spectrum when $φ$ is a parabolic or elliptic automorphism of the unit disc. In the case of a hyperbolic automorphism $φ$, exact expressions for the spectral radii of invertible weighted composition operators acting on the Bloch and Dirichlet spaces are derived.
