Compact elements and the hypocompact radical of crossed products
We characterize the compact elements and the hypocompact radical of a crossed product $C_0(X)\times _\phi \mathbb Z$ , where X is a locally compact metrizable space and $\phi :X\rightarrow X$ is a homeomorphism, in terms of the corresponding dynamical system $(X,\phi )$ .- 7 January 2025

Ideals with approximate unit in semicrossed products
We characterize the ideals of the semicrossed product C0(X) × ϕ Z+, associated with suitable sequences of closed subsets of X, with left (resp. right) approximate unit. As a consequence, we obtain a complete characterization of ideals with left (resp. right) approximate unit under the assumptions that X is metrizable and the dynamical system (X, ϕ) contains no periodic points.

Compact multiplication operators on semicrossed products
We characterize the compact multiplication operators on a semicrossed product $C_0(X)\times _\phi \mathbb Z_+$ in terms of the corresponding dynamical system. We also characterize the compact elements of this algebra and determine the ideal they generate.- 1 January 2023

Topological radicals of semicrossed products
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 hypocompact radical if and only if the Fourier coefficients of A vanish on the closure of the recurrent points and the 0-Fourier coefficient vanishes also on the largest perfect subset of X.
