Motivated by a problem in approximation theory, we find a necessary and sufficient condition for a model (backward shift invariant) subspace $K_\varTheta = H^2\ominus \varTheta H^2$ of the Hardy

We characterize the model spaces KΘ in which functions with smooth boundary extensions are dense. It turns out that such approximation is possible if and only if the singular measure associated to

• Mathematics

We give an abstract approach to approximations with a wide range of regularity classes X in spaces of pseudocontinuable functions K p θ, where θ is an inner function and p > 0. More precisely, we
Cyclic inner functions in growth classes and applications to approximation problems
It is well-known that for any inner function θ deﬁned in the unit disk D the following two conditons: ( i ) there exists a sequence of polynomials { p n } n such that lim n →∞ θ ( z ) p n ( z ) = 1

A Schwarz function on an open domain Ω is a holomorphic function satisfying S(ζ) = ζ on Γ, which is part of the boundary of Ω. Sakai in 1991 gave a complete characterization of the boundary of a
