Fourier transform, Schrödinger representation, and Heisenberg modules

Abstract

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