Abelian self-commutators in finite factors

Gabriel Nagy

An abelian self-commutator in a C*-algebra $A$ is an element $A$ that can be written as $A = X^{*} X - X X^{*}$ , with $X \in A$ such that $X^{*} X$ and $X X^{*}$ commute. It is s…

Spectral Symmetry in II_1 Factors

Sang Hyun Kim, Gabriel Nagy

A self-adjoint element in a finite AW*-factor is spectrally symmetric, if its spectral measure under the quasitrace is invariant under the change of variables $t ⟼ - t$ . We…

A note on idempotents in finite AW*-factors

Gabriel Nagy

We prove that the value of the quasi-trace on an idempotent element in a AW*-factor of type II_1 is the same as the dimension of its left (or right) support.
