Measure Theory in Noncommutative Spaces

Steven Lord ; Fedor Sukochev

Symmetry, integrability and geometry: methods and applications, Tome 6 (2010)

Résumé

The integral in noncommutative geometry (NCG) involves a non-standard trace called a Dixmier trace. The geometric origins of this integral are well known. From a measure-theoretic view, however, the formulation contains several difficulties. We review results concerning the technical features of the integral in NCG and some outstanding problems in this area. The review is aimed for the general user of NCG.

Détail

Keywords: Dixmier trace; singular trace; noncommutative integration; noncommutative geometry; Lebesgue integral; noncommutative residue.
