Title: | Facets of congruence distributivity in Goursat categories | Authors: | Gran, Marino Rodelo, Diana Nguefeu, Idriss Tchoffo |
Keywords: | Mal'tsev categories; Goursat categories; Congruence distributive varieties; Shifting Lemma; Triangular Lemma; Trapezoid Lemma | Issue Date: | 2020 | Publisher: | Elsevier | Project: | UIDB/00324/2020 | Serial title, monograph or event: | Journal of Pure and Applied Algebra | Volume: | 224 | Issue: | 10 | Abstract: | 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 Lemma in universal algebra. We then give new characterisations of equivalence distributive Goursat categories (which extend 3-permutable varieties) through variations of the Triangular and Trapezoid Lemmas involving reflexive and positive relations. | URI: | https://hdl.handle.net/10316/89452 | DOI: | 10.1016/j.jpaa.2020.106380 | Rights: | embargoedAccess |
