Abstract

Let GG be a locally compact second countable groupoid with a fixed Haar system λ={λu}uG0\lambda=\{\lambda^{u}\}_{u\in G^{0}} and (Φ,Ψ)(\Phi,\Psi) be a complementary pair of NN-functions satisfying Δ2\Delta_{2}-condition. In this article, we introduce the continuous field of Orlicz space (L0Φ,Δ1)(L^{\Phi}_{0},\Delta_{1}) and provide a sufficient condition for the space of continuous sections vanishing at infinity, denoted E0ΦE^{\Phi}_{0}, to be an Banach algebra under a suitable convolution. Further, the condition for a closed Cb(G0)C_{b}(G^{0})-submodule II of E0ΦE^{\Phi}_{0} to be a left ideal is established. Moreover, we provide a groupoid analogue of the characterization of the space of convolutors of Morse-Transue space for locally compact groups.
