Translated title:
Topics in the theory of Banach Algebras and Operator Algebras: The Jacobson Radical of a nest Algebra and of a semicrossed product.
Summary:
In this MSc thesis the Jacobson radical of a nest algebra and of a semicrossed product are fully described. First, various characterizations of the Jacobson radical of an arbitrary algebra are given. Afterwards, Ringrose's characterization of the radical of a nest algebra is described using the Jacobson radical of a nest algebra of a finite nest. Finally, we characterise the Jacobson radical of a semicrossed product using basic results from the theory of dynamical systems.
