Trace mappings on quasi-Banach modulation spaces and applications to pseudo-differential operators of amplitude type

We deduce trace properties for modulation spaces (including certain Wiener-amalgam spaces) of Gelfand–Shilov distributions.We use these results to show that [Formula: see text]dos with amplitudes in suitable spaces, agree normal type whose symbols belong (other) spaces. In particular we extend earlier include quasi-Banach also apply our on Schatten-von Neumann and nuclear
