The homology of principally directed ordered groupoids

B. O. Bainson, N. D. Gilbert

We present some homological properties of a relation $β$ on ordered groupoids that generalises the minimum group congruence for inverse semigroups. When $β$ is a transitive relatio…

Cohomology and extensions of ordered groupoids

B. O. Bainson, N. D. Gilbert

We adapt and generalise results of Loganathan on the cohomology of inverse semigroups to the cohomology of ordered groupoids. We then derive a five-term exact sequence in cohomolog…
