Joint torsion of several commuting operators

Jens Kaad

We introduce the notion of joint torsion for several commuting operators satisfying a Fredholm condition. This new secondary invariant takes values in the group of invertibles of a…

Invariance results for pairings with algebraic K-theory

Jens Kaad

To each algebra over the complex numbers we associate a sequence of abelian groups in a contravariant functorial way. In degree (m-1) we have the m-summable Fredholm modules over t…
