In this note we show that a combinatorial model of Kirchberg algebras in theUCT, namely the Katsura algebras O_{AB}, can be expressed both as groupoidC*-algebras and as inverse semigroup crossed products. We use this picture toobtain results about simplicity, pure infiniteness and nuclearity of O_{AB}using different methods than those used by Katsura.

Representing Kirchberg algebras as inverse semigroup crossed products
