Higher dimensional Bott classes and the stability of rotation relations

Sayan Chakraborty, Jiajie Hua

Let $\Theta =({\theta }_{jk}{)}_{n\times n}$ be a real skew-symmetric $n\times n$ matrix for $n\ge 2$. Under some mild non-integrality conditions on $\Theta ,$ we construct Rieffel-type projections as…
