Abstract

We introduce global wave-front sets WFB(f)\operatorname{WF}_{{\mathcal B}} (f), fS(Rd)f\in {\mathscr S}^\prime(\textbf{R}^d), with respect to suitable Banach or Fr\'echet spaces B{\mathcal B}. An important special case is given by the modulation spaces B=M(ω,B){\mathcal B}=M(\omega,\mathscr B), where ω\omega is an appropriate weight function and B\mathscr B is a translation invariant Banach function space. We show that the standard properties for known notions of wave-front set extend to WFB(f)\operatorname{WF}_{{\mathcal B}} (f). In particular, we prove that micro locality and microellipticity hold for a class of globally defined pseudo-differential operators Opt(a)\operatorname{Op}_t(a), acting continuously on the involved spaces.
