The injective tensor product of normal representable bimodules over von Neumann algebras is shown to be normal. The usual Banach module projective tensor product of central representable bimodules over an Abelian C∗-algebra is shown to be representable. A normal version of the projective tensor product is introduced for central normal bimodules.

Let G be a locally compact group, and take p ∈ (1,∞). We prove that the Banach left L(G)module L(G) is injective (if and) only if the group G is amenable. Our proof uses the notion of multi-norms. We also develop the theory of multi-normed spaces.

In this paper we investigate some properties of φ−multipliers on Banach algebras. We also consider φ−multipliers in the general topological module setting. We discuss the φ−strict and φ−uniform topologies on Mφ(A). Mathematics Subject Classification: 47B48,47C05, 46H05, 46H25

Let Γ be an arithmetic group contained in a semigroup S that commensurates Γ and let H be the corresponding Hecke algebra. Given a p-adic analytic family of Banach S-modules varying over an affinoid space Ω and an H-eigenclass ζ in the homology of Γ with coefficients in one member of the family, we give an explicit construction of a p-adic analytic deformation of ζ along some Zariski closed sub...

Abstract We introduce a notion of topologically flat locally convex module, which extends the Banach module and is well adapted to nonmetrizable setting (and especially DF-modules). Using this notion, we amenable algebras show that complete barrelled DF-algebra if only it Johnson amenable, extending thereby Helemskii–Sheinberg’s criterion for algebras. As an application, completely characterize...

We construct a KK-theory for Banach algebras, equivariant with respect to the action of a groupoid. We prove the Baum–Connes conjecture with commutative coefficients for hyperbolic groups and for the Poincaré groupoids of foliations with a compact base and a longitudinal Riemannian metrics with negative sectional curvature.
