Abstract

We investigate the lifting property of modulation spaces and construct explicit isomorphisms between them. For each weight function ω and suitable window function φ, the Toeplitz operator (or localization operator) Tpφ(ω) is an isomorphism from \(M_{({\omega _0})}^{p,q}\), onto \(M_{({\omega _0}/\omega )}^{p,q}\) for every p, q ∈ [1,∞] and arbitrary weight function ω0. The methods involve the pseudo-differential calculus of Bony and Chemin and the Wiener algebra property of certain symbol classes of pseudo-differential Operators.
