Abstract

If p ⁣:BGp \colon \mathcal B\to G is a Fell bundle over an \'etale groupoid, then we show that there is an norm reducing injective linear map j ⁣:Cr(G;B)Γ0(G;B)j \colon C^*_r(G;\mathcal B)\to \Gamma_{0}(G;\mathcal B) generalizing the well know map j ⁣:Cr(G)C0(G)j \colon C^*_{r}(G)\to C_{0}(G) in the case of an \'etale groupoid.
