For a locally compact group G, let A(G) denote its Fourier algebra and, for p ∈ (1,∞), let Ap(G) be the corresponding Figà-Talamanca–Herz algebra. For amenable G and p, p ∈ (1,∞) such that 1 p + 1 p , we show that Ap(G) ∩Ap′(G) = A(G).

in this paper we define an order structure on the $p$-operator projective tensor product of herz algebras and we show that the canonical isometric isomorphism between $a_p(gtimes h)$ and $a_p(g)widehat{otimes}^p a_p(h)$ is an order isomorphism for amenable groups $g$ and $h$.

Using the recently developed notion of a Herz-Schur multiplier C*-dynamical system we introduce weak amenability C*- and W*-dynamical systems. As special case recover Haagerup's characterisation discrete group. We also consider generalisation Fourier algebra its multipliers to crossed products.

For the characterization of multipliers Lp(Rd) or more generally, Lp(G) for some locally compact Abelian group G, so-called Figa-Talamanca–Herz algebra Ap(G) plays an important role. Following Larsen’s book, we describe as bounded linear operators that commute with translations. The main result this paper is Ap(G). In fact, demonstrate it coincides space Lp(G),?·?p. Given a multiplier T (Ap(G),...

Given a C ⁎ -dynamical system ( A , G α ) with discrete group, Schur -multipliers and Herz–Schur are used to implement approximation properties, namely exactness the strong operator property (SOAP), of ⋊ r . The resulting characterisations SOAP generalise corresponding statements for reduced group -algebra.

We show that the multiplier algebra of the Fourier algebra on a locally compact group G can be isometrically represented on a direct sum on non-commutative L spaces associated to the right von Neumann algebra of G. If these spaces are given their canonical Operator space structure, then we get a completely isometric representation of the completely bounded multiplier algebra. We make a careful ...

For a locally compact group G and p ∈ (1,∞), we define Bp(G) to be the space of all coefficient functions of isometric representations of G on quotients of subspaces of Lp spaces. For p = 2, this is the usual Fourier–Stieltjes algebra. We show that Bp(G) is a commutative Banach algebra that contractively (isometrically, if G is amenable) contains the Figà-Talamanca–Herz algebra Ap(G). If 2 ≤ q ...
