Abstract:
In this talk, we give an elementary proof of the approximation theorem established by A. Matheson for analytic Lipschitz spaces λα. Our approach allows us to extend this approximation theorem to \cDω∩λα, where \cDω denotes superharmonically weighted Dirichlet spaces (including standard Dirichlet spaces). As a consequence, we give a complete description of closed ideals of the Banach algebra \cDω∩λα. This extends previous results obtained A. Matheson and B. Bouya.
