We consider weakenings of normality in $Ψ$ -spaces and prove that the existence of a MAD family whose $Ψ$ -space is almost-normal is independent of \textsf{ZFC}. We also construct a…

Dixmier traces for discrete pseudo-differential operators

Duván Cardona, César del Corral, Vishvesh Kumar

In this paper we provide sharp results for the Dixmier traceability of discrete pseudo-differential operators on $ℓ^{2} (Z^{n})$ . In this setting, we introduce a suitable no…
