Index pairings for ${\mathbb{R}}^n$-actions and Rieffel deformations

Andreas Andersson

With an action $\alpha$ of ${\mathbb{R}}^n$ on a $C^{\ast }$-algebra $A$ and a skew-symmetric $n\times n$ matrix $\Theta$ one can consider the Rieffel deformation $A_{\Theta }$ of $A$, which is a $C^{\ast }$-alge…
