A Strict Positivstellensatz for Enveloping Algebras
Konrad Schmuedgen
Let G be a connected and simply connected real Lie group with Lie algebra g. Semialgebraic subsets of the unitary dual of G are defined and a strict Positivstellensatz for positive…

A Strict Positivstellensatz for the Weyl Algebra
Konrad Schmuedgen
Let be an element of the Weyl algebra which is given by a strictly positive operator in the Schr"odinger representation. It is shown that, under some conditions, there e…

Examples of twisted cyclic cocycles from covariant differential calculi
Konrad Schmuedgen, Elmar Wagner
For two covariant differential *-calculi, the twisted cyclic cocycle associated with the volume form is represented in terms of commutators [F,ρ(x)] for some self-adjoint operator…
