| Abstract: | For two covariant differential *-calculi, the twisted cyclic cocycle associated with the volume form is represented in terms of commutators
![$$\left {\mathcal{F},\rho \left( x \right)} \right]$$](/content/x418656812106442/11005_2004_Article_5145401_TeX2GIFIE1.gif)
for some self-adjoint operator
and some *-representation  of the underlying *-algebra. |
