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 for all z ∈ D , and ( ii ) sup n k θp n k ∞ < ∞ , are incompatible, i.e., cannot be satisfied simultaneously. In this note we discuss and apply a consequence of a result by Thomas Ransford from [13], which shows that if we relax the second condition to allow for arbitrarily slow growth of the sequence…

An abstract approach to approximations in spaces of pseudocontinuable functions

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

Abstract It is known that if $S(z)$ is a non-constant singular inner function defined on the unit disk, then $\min _{|z|\le r}|S(z)|\to 0$ as $r\to 1^-$ . We show that the convergence can be

In this paper we construct a singular inner function whose polynomial multiples are dense in the little Bloch space qo . To do this we construct a singular measure on the unit circle with "best

In this note we summarize some necessary and sufficient conditions for subspaces invariant with respect to the backward shift to contain smooth functions. We also discuss smoothness of moduli of
