Groupoids and the Associative Law VII. (Semigroup Distance of SH-Groupoids)
Szasz-Hájek groupoids are those groupoids that contain just one non-associative (ordered) triple of elements. These groupoids were studied by G. Szász. The present short note is concerned with semigroup distances of SH-...

Locally Hausdorff tight groupoids generalised
We extend Exel’s ample tight groupoid construction to non-ample groupoids, even in the general locally Hausdorff case.

Semigroup Distances of Finite Groupoids
The simplest cases of non-associative groupoids are presented by groupoids (so called SH-groupoids) having just one non-associative (ordered) triple of elements. In this paper only SH-groupoids having the simplest ...

Groupoids and the Associative Law VIIA. (SH-Groupoids of Type (A,B,A) and their Semigroup Distances)
Szász-Hájek groupoids (shortůy SH-groupoids) are those groupoids that contain just one non-associative (ordered) triple of elements. These groupoids were studied by G. Szász (see (10) amd (11)), P. Hájek (see (2) a...

Reconstructing étale groupoids from semigroups
We unify various étale groupoid reconstruction theorems such as the following: Kumjian and Renault's reconstruction from a groupoid C∗-algebra, Exel's reconstruction from an ample inverse semigroup, Steinberg's reconstruction from a...
