Popis: This paper is a contribution to the theory of what might be termed $0$-dimensional non-commutative spaces. We prove that associated with each inverse semigroup $S$ is a Boolean inverse semigroup presented by the abstract versions of the Cuntz-Krieger relations. We call this Boolean inverse semigroup the Exel completion of $S$ and show that it arises from Exel's tight groupoid under non-commutative Stone duality.
Comment: This revised version of the paper contains a genearalization suggested by Enrique Pardo (using a result of Lisa Orloff Clark) and answers some questions posed by Ruy Exel
