Topological Radicals of Semicrossed Products
G. Andreolas, M. Anoussis, C. Magiatis
We characterize the hypocompact radical of a semicrossed product in terms of properties of the dynamical system. We show that an element A of a semicrossed product is in the hypoco…

Compact multiplication operators on semicrossed products
G. Andreolas, M. Anoussis, C. Magiatis
We characterize the compact multiplication operators on a semi-crossed product in terms of the corresponding dynamical system. We also characterize the compact elements of this alg…
