Constructing non-AMNM weighted convolution algebras for every semilattice of infinite breadth

Yemon Choi, Mahya Ghandehari, Hung Le Pham

The AMNM property for commutative Banach algebras is a form of Ulam stability for multiplicative linear functionals. We show that on any semilattice of infinite breadth, one may co…

Characterisations of Fourier and Fourier--Stieltjes algebras on locally compact groups

Anthony To-Ming Lau, Hung Le Pham

Motivated by the beautiful work of M. A. Rieffel (1965) and of M. E. Walter (1974), we obtain characterisations of the Fourier algebra $A (G)$ of a locally compact group $G$ in term…

Idempotents of small norm

Jayden Mudge, Hung Le Pham

Let $Γ$ be a locally compact group. We answer two questions left open in [7] and [9]: i) For abelian $Γ$ , we prove that if $χ_{S} \in B (Γ)$ is an idempotent with norm $\left\|χ_S \ri…

Preduals of semigroup algebras

Matthew Daws, Hung Le Pham, Stuart White

For a locally compact group $G$ , the measure convolution algebra $M (G)$ carries a natural coproduct. In previous work, we showed that the canonical predual $C_{0} (G)$ of $M (G)$ is th…
