Invariant subspaces and closed ideals in banach spaces and algebras of functions

Objective



Research objectives and content
The project lies in the border area between functional analysis and function theory and consists of two topics.
Firstly, I will study the biinvariant subspaces of certain weighted spaces of functions on the circle. I expect either to obtain a characterization of these in terms of zero sets and inner factors or to show that a characterization in these terms is not possible.
Secondly, I will investigate the closed ideals in non-separable Banach algebras of analytic functions on the unit disc with the main emphasis on the Lipschitz algebras. For these I expect to show that, given a certain set of conditions, there exists a smallest closed ideal which satisfies these. Moreover, I expect to give a Beurling-Rudin characterization of the weak-star closed ideals in these algebras.
Training content (objective. benefit and expected impact)
The main methods that will be used in the project are the weighted hyper-distributions and the Carleman transform. Prof. J. Esterle from the host institution is a leading expert in these techniques and, through the training, I expect to gain insight into how to apply them.
