The concept of Abbott groupoid is introduced in this paper. It is shown that such a groupoid is a join semilattice with greatest element. A characterization of implication algebras is given.

Introduction In a previous paper ([1]) we showed how a fibration of groupoids gave rise to a six-term exact sequence (three terms of which were groups and three were sets) and that this exact sequence included the bottom end of the topologists' exact sequence of a fibration of spaces, and also in the non-abelian cohomology of a group 0 the six-term ...

This paper is an immediate continuation of a series of papers (now four) [ibid. 10, 109-124 (1992; Zbl 0814.20052); 11, 113-123 (1992; Zbl 0814.20053); 16, 71-82 (1995; Zbl 0849.20050)], where the authors investigate left closed subgroupoids of left cancellative groupoids, left strongly dense subgroupoids of left distributive groupoids, their ...
