Charalampos Magiatis
We characterize the ideals of the semicrossed product with left (resp. right) approximate unit.

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…
