(Generalized) Spine Subalgebras of Fourier-Stieltjes algebras and their Homomorphisms

Nico Spronk, Ross Stokke, Aasaimani Thamizhazhagan

For any upper semilattice $D$ of locally precompact topologies on a locally compact group $G$ , we define an associated generalized spine subalgebra $A_{D}^{*} (G)$ of the…

On Beurling measure algebras

Ross Stokke

We show how the measure theory of regular compacted-Borel measures defined on the $δ$ -ring of compacted-Borel subsets of a weighted locally compact group $(G, ω)$ provides a compati…

Norm-multiplicative homomorphisms of Beurling algebras

Matthew E. Kroeker, Alexander Stephens, Ross Stokke +1

We introduce and study "norm-multiplicative" homomorphisms $φ : L^{1} (F) \to M_{r} (G)$ between group and measure algebras, and $φ: {\cal L}^1(ω_F) \rightarrow {\ca…

Homomorphisms of Fourier-Stieltjes algebras

Ross Stokke

Every homomorphism $φ : B (G) \to B (H)$ between Fourier-Stieltjes algebras on locally compact groups $G$ and $H$ is determined by a continuous mapping $α: Y \rightarrow Δ(B(G…

Fourier spaces and completely isometric representations of Arens product algebras

Ross Stokke

Motivated by the definition of a semigroup compactification of a locally compact group and a large collection of examples, we introduce the notion of an (operator) "homogeneous lef…

Extension of derivations, and Connes-amenability of the enveloping dual Banach algebra

Yemon Choi, Ebrahim Samei, Ross Stokke

If $D : A \to X$ is a derivation from a Banach algebra to a contractive, Banach $A$ -bimodule, then one can equip $X^{**}$ with an $A^{**}$ -bimodule structure, such that the second tr…

Matrix coefficients of unitary representations and associated compactifications

Nico Spronk, Ross Stokke

We study, for a locally compact group $G$ , the compactifications $(π, G^{π})$ associated with unitary representations $π$ , which we call {\it $π$ -Eberlein compactifications}. We also…

Biflatness and Pseudo-Amenability of Segal algebras

Ebrahim Samei, Nico Spronk, Ross Stokke

We investigate generalized amenability and biflatness properties of various (operator) Segal algebras in both the group algebra, L1(G), and the Fourier algebra, A(G), of a locally…
