Abstract

We investigate and review how Fourier transform is involved in the analysis of a twisted group algebra L1(G,σ)L^1(G, \sigma) for G=Γ^×ΓG=\widehat{\Gamma}\times \Gamma and σ:G×GT\sigma:G\times G \to \mathbb{T} 2- cocycle where Γ\Gamma is a locally compact abelian group and Γ^\widehat{\Gamma} its Pontryagin dual. By weaving the Schr\"{o}dinger representation and Fourier transform, we construct the dual equivalence bimodule of the Heisenberg bimodule generated by the dual Schr\"{o}dinger representation and observe several relations between them including the application of noncommutative solitons.
