Smooth and weak synthesis of the anti-diagonal in Fourier algebras of Lie groups

B. Doug Park, Ebrahim Samei

Let $G$ be a Lie group of dimension $n$ , and let $A (G)$ be the Fourier algebra of $G$ . We show that the anti-diagonal $Δ ˇ_{G} = {(g, g^{- 1}) \in G \times G ∣ g \in G}$ is both a…

Weak amenability of Fourier algebras on compact groups

Brian E. Forrest, Ebrahim Samei, Nico Spronk

We give for a compact group G, a full characterisation of when its Fourier algebra A(G) is weakly amenable: when the connected component of the identity G_e is abelian. This condit…

Amenability properties of the centres of group algebras

Ahmadreza Azimifard, Ebrahim Samei, Nico Spronk

Let G be a locally compact group, and ZL1(G) be the centre of its group algebra. We show that when $G$ is compact ZL1(G) is not amenable when G is either nonabelian and connected,…

Convolutions on compact groups and Fourier algebras of coset spaces

Brian E. Forrest, Ebrahim Samei, Nico Spronk

In this note we study two related questions. (1) For a compact group G, what are the ranges of the convolution maps on A(GXG) given for u,v in A(G) by $u X v ∣ - > u * v^{'} ($ v'(s)=v(s^{…
