Abstract

We discuss the boundary behavior of functions in star-invariant subspaces (BH2), where B is a Blaschke product. Extending some results of Ahern and Clark, we are particularly interested in the growth rates of functions at points of the spectrum of B where B does not admit a derivative in the sense of Carathéodory.
