Abstract

We deduce one-parameter group properties for pseudo-differential operators Op(a)\operatorname{Op} (a), where aa belongs to the class Γ(ω0)\Gamma ^{(\omega _0)}_* of certain Gevrey symbols. We use this to show that there are pseudo-differential operators Op(a)\operatorname{Op} (a) and Op(b)\operatorname{Op} (b) which are inverses to each others, where aΓ(ω0)a\in \Gamma ^{(\omega _0)}_* and bΓ(1/ω0)b\in \Gamma ^{(1/\omega _0)}_*. We apply these results to deduce lifting property for modulation spaces and construct explicit isomorpisms between them. For each weight functions ω,ω0\omega ,\omega _0 moderated by GRS submultiplicative weights, we prove that the Toeplitz operator (or localization operator) Tp(ω0)\operatorname{Tp} (\omega _0) is an isomorphism from M(ω)p,qM^{p,q}_{(\omega )} onto M(ω/ω0)p,qM^{p,q}_{(\omega /\omega _0)} for every p,q(0,]p,q \in (0,\infty ].
