Extended zeta-function residues on principal ideals

Yongqiang Tian, Alexandr Usachev

We study extended zeta-function residues on principal ideals of compact operators and their connections with Dixmier traces. We establish a Lidskii-type formula for continuous sing…

Dixmier-type traces on semifinite symmetric spaces

Galina Levitina, Alexandr Usachev

We prove that a normalised linear functional on certain semifinite symmetric spaces respects tail majorisation if and only if it is a Dixmier-type trace.
