Corners of Cuntz-Krieger algebras
Published 19 Sep 2012 in math.OA | (1209.4336v3)
Abstract: We show that if $A$ is a unital $C*$-algebra and $B$ is a Cuntz-Krieger algebra for which $A\otimes\mathbb{K} \cong B\otimes\mathbb{K}$, then $A$ is a Cuntz-Krieger algebra. Consequently, corners of Cuntz-Krieger algebras are Cuntz-Krieger algebras.
