The Stable Exotic Cuntz Algebras are Higher-Rank Graph Algebras

Jeffrey L. Boersema, Sarah L. Browne, Elizabeth Gillaspy

For each odd integer $n\ge 3$, we construct a rank-3 graph ${\Lambda }_n$ with involution ${\gamma }_n$ whose real C*-algebra $C_{\mathbb{R}}^{\ast }({\Lambda }_n,{\gamma }_n)$ is stably isomorphic to the exotic Cuntz a…
