Crossed products by Hecke pairs I: *-algebraic theory

Rui Palma

We develop a theory of crossed products by "actions" of Hecke pairs $(G, Γ)$ , motivated by applications in non-abelian $C^{*}$ -duality. Our approach gives back the usual crossed prod…

Quasi-symmetric group algebras and C*-completions of Hecke algebras

Rui Palma

We show that for a Hecke pair $(G, Γ)$ the $C^{*}$ -completions $C^{*} (L^{1} (G, Γ))$ and $p C^{*} (G ˉ) p$ of its Hecke algebra coincide whenever the group algebra $L^{1} (G ˉ)$ satisfies…

On enveloping C*-algebras of Hecke algebras

Rui Palma

We give a sufficient condition for a $^{*}$ -algebra with a specified basis to have an enveloping $C^{*}$ -algebra. Particularizing to the setting of a Hecke algebra $\h(G,\gm)$, we show…
