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…
Unavoidable subprojections in union-closed set systems of infinite breadth
Yemon Choi, Mahya Ghandehari, Hung Le Pham
We consider union-closed set systems with infinite breadth, focusing on three particular configurations , and ${\mathcal T}_{…
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 of a locally compact group in term…
Idempotents of small norm
Jayden Mudge, Hung Le Pham
Let be a locally compact group. We answer two questions left open in [7] and [9]: i) For abelian , we prove that if is an idempotent with norm $\left\|χ_S \ri…
Isometries between quantum convolution algebras
Matthew Daws, Hung Le Pham
Given locally compact quantum groups $\G_1$ and $\G_2$, we show that if the convolution algebras $L^1(\G_1)$ and $L^1(\G_2)$ are isometrically isomorphic as algebras, then $\G_1$ i…
Preduals of semigroup algebras
Matthew Daws, Hung Le Pham, Stuart White
For a locally compact group , the measure convolution algebra carries a natural coproduct. In previous work, we showed that the canonical predual of is th…
