Crossed products and twisted $k$-graph algebras

Nathan Brownlowe, Valentin Deaconu, Alex Kumjian +1

An automorphism $\beta$ of a $k$-graph $\Lambda$ induces a crossed product $C^{\ast }(\Lambda ){⋊}_{\beta }\mathbb{Z}$ which is isomorphic to a $(k+1)$-graph algebra $C^{\ast }(\Lambda {\times }_{\beta }\mathbb{Z})$. In this…
