Abstract
We characterize the connected components of the subset of formed by the products , where is Carleson-Newman Blaschke product and is an invertible function. We use this result to show that, except for finite Blaschke products, no inner function in the little Bloch space is in the closure of one of these components. Our main result says that every inner function can be connected with an element of within the set of products , where is inner and is invertible. We also study some of these issues in the context of Douglas algebras.
