Invariant Subspaces in the Dual of $A_{c b} (G)$ and $A_{M} (G)$

Brian Forrest, John Sawatzky, Aasaimani Thamizhazhagan

Let $G$ be a locally compact group. In this paper, we study various invariant subspaces of the duals of the algebras $A_{M} (G)$ and $A_{c b} (G)$ obtained by taking the closure of the…

Arens regularity of ideals in $A (G)$ , $A_{c b} (G)$ and $A_{M} (G)$

Brian Forrest, John Sawatzky, Aasaimani Thamizhazhagan

In this paper, we look at the question of when various ideals in the Fourier algebra $A (G)$ or its closures $A_{M} (G)$ and $A_{c b} (G)$ in, respectively, its multiplier and $c b$ -multi…

Amenability constants of central Fourier algebras of finite groups

John Sawatzky

We consider amenability constants of the central Fourier algebra $Z A (G)$ of a finite group $G$ . This is a dual object to $Z L^{1} (G)$ in the sense of hypergroup algebras, and as such…
