Facets of congruence distributivity in Goursat categories
Marino Gran, Diana Rodelo, Idriss Tchoffo Nguefeu
We give new characterisations of regular Mal'tsev categories with distributive lattice of equivalence relations through variations of the so-called Triangular Lemma and Trapezoid L…
Variations of the Shifting Lemma and Goursat categories
Marino Gran, Diana Rodelo, Idriss Tchoffo Nguefeu
We prove that Mal'tsev and Goursat categories may be characterised through stronger variations of the Shifting Lemma, that is classically expressed in terms of three congruences $R…
Goursat completions
Diana Rodelo, Idriss Tchoffo Nguefeu
We characterize categories with weak finite limits whose regular completions give rise to Goursat categories.
Some remarks on connectors and groupoids in Goursat categories
Marino Gran, Diana Rodelo, Idriss Tchoffo Nguefeu
We prove that connectors are stable under quotients in any (regular) Goursat category. As a consequence, the category of connectors in is a…
