Abstract

For two covariant differential *-calculi, the twisted cyclic cocycle associated with the volume form is represented in terms of commutators \(\left[ {\mathcal{F},\rho \left( x \right)} \right]\) for some self-adjoint operator \(\mathcal{F}\) and some *-representation ρ of the underlying *-algebra.
